The new Scottish Premier League season for 2012/13 gets up and running this weekend with two, rather than one, new sides introduced into the division.

Ross County manager Derek Adams has urged his team to continue their progression by making their mark in the Scottish Premier League this season. The First Division champions make their debut in the top flight this term, opening the campaign at home to Motherwell on Saturday.

"Season on season, we've moved on," Adams said ahead of the season's start. "If we progress the way we've progressed over the number of years we've been here, we'll do well."

County have upgraded their Victoria Park ground for the top flight and Adams replenished his squad with players who have plenty of SPL experience, including Ross Tokely. The veteran defender ended a 16-year spell at County's Highland rivals Inverness Caledonian Thistle.

"We're thoroughly looking forward to the start of the season," said Adams. "The stadium's looking great, the players have prepared well for the season. We want to do as well as we can in the SPL, we want to finish as high as possible. Last season was exactly the same. We're going there to pick up as many points as we possibly can.

"We've taken in a number of players over the summer and Inverness have taken a number of our players over the years. We've now taken the likes of Russell Duncan, Grant Munro, Ross Tokely and Iain Vigurs. It'll be good for them to go back to Inverness in the derby match and hopefully they'll do well here."

General manager Ranald Gilbert is confident the Staggies are in robust shape off the park ahead of their SPL introduction.

"It's no secret, we're very fortunate," he said. "The board of directors as a whole and the chairman have been a fantastic support to the club right through the rise through the leagues. We're looking forward and indeed upwards with renewed confidence and optimism. There are obviously challenges, but there are certainly opportunities as well.

"All clubs and all fans are eyeing those European spots and thinking that there's a definite pathway forward there. Football fans as a whole are looking forward to the action being on the pitch not off it."

Chief executive Scot Gardiner says Dundee are ready for "a great adventure" as they make their top-flight return after seven years away. Dundee were late replacements after Rangers headed for liquidation.

Gardiner said: "We would have liked a few more weeks' notice, but we are where we are. If we bring in the right players, by the end of August, I think you'll see a good Dundee team ready to make a right go of it."

Manager Barry Smith had already signed three new players and made Carl Finnigan's loan from St Johnstone permanent in preparation for another assault on promotion.

But they waited until confirmation of a new Scottish Premier League television deal before adding former Brussels defender Davide Grassi and released Bradford City striker Mark Stewart.

"We had a First Division budget and we were working to a First Division budget until two weeks past Monday. Then we got the decision we were hoping for, but it's been absolutely manic and meetings until late in the night with agents pretty much from all over Europe. Barry feels that we certainly need six. We'll bring in six and that might not be right up until the end of the window.

"We can't make many mistakes, so we've got to make sure they are the right boys that come in."

Gardiner said bringing the club up to SPL standard behind the scenes will eat into any extra income they will receive.

"We need to manage it very carefully and not put the club at risk," he said. "This should be a chance for us to build a bedrock and platform for the club going forward."

Gardiner thinks Dundee's return to the SPL, and their rivalry with neighbours United, will be "phenomenal" for the city.

He predicted that up to 3,000 Dundee fans would travel to Kilmarnock for their opening fixture.

Gardiner thought that Celtic would be strong favourites for the title but pointed out that other clubs had been unable to strengthen significantly because of a lack of finance.

"There's a little mix of trepidation, because we had built a good squad and were planning to win the First Division, and a tremendous amount of excitement," he said.

Dundee have already played one competitive fixture, with Smith having to name himself as a substitute for his injury-hit squad as they struggled to overcome Third Division Peterhead on penalties after a 0-0 draw in the Scottish Communities League Cup.

The manager said his side also had to learn from their derby defeat in a pre-season friendly, when more than 10,000 fans watched United win 3-0.

"I think the massive difference was how clinical United were," he said. "But, in general terms, I think we competed well for 70 minutes, but the wee lapses in concentration are what we'll need to work on.

"We have to work harder than we ever have before to make sure we remain in the Premier League. It is a great opportunity for myself and the players to go and do well in the Premier League. We've not had a lot of time to strengthen the squad, but I'm sure, come Saturday, everybody will be ready to play their part in getting off to a good start."

Rangers' financial collapse and re-birth in Division Three means that the Scottish Premier League welcomes two new clubs instead of one this season. Statistics alone dictate that this should substantially increase the chances of one of the new boys finishing last of 12 and dropping straight back down.

That one of them, Dundee, has only had three weeks to prepare for stepping up a level, having finished a proverbial country mile behind runaway champions Ross County, makes relegation for one of them even more of a possibility. It certainly makes the Dark Blues' task that bit more daunting.

County finished 24 points ahead of Dundee - four more than Celtic managed over Rangers even with the help of a 10-point deduction for the latter going into administration as their financial troubles came to a head.

County boss Derek Adams has lost forward Michael Gardyne and defender Gary Miller to SPL rivals Dundee United and St Johnstone respectively as the Staggies make their top flight debut 18 years after stepping up from the Highland League to the Third Division with neighbours Inverness Caledonian Thistle.

However, the Dingwall outfit have added players of SPL experience, such as veteran defender Ross Tokely from Caley Thistle and former Dundee United defender Mihael Kovacevic.

Dundee, in contrast, had been preparing for another push for promotion, Iain Davidson and John Baird arriving from Division One rivals Raith Rovers and gambling on the potential of talented 21-year-old defender Declan Gallagher from Clyde. Battering the phones to agents long into the night has so far unearthed two players with SPL experience - former Aberdeen defender Davide Grassi and ex-Falkirk forward Mark Stewart - a quarter of what their manager believes will be necessary to compete in the top flight.
