Derek Adams is not too big for his boots to admit he got something wrong and reverted to a more solid approach after realising his Ross County players were not suited to an expansive game. County have kept three clean sheets in four games since the change in tactics and are unbeaten in seven games. Tomorrow they welcome Motherwell with the second placed side just five points ahead of the hosts. County made a good start to the season with five clean sheets delivered in their first six games. However, Adams felt they opened up too much in the middle of the season. Their games with tomorrow's visitors highlights the trend - County held Motherwell to a goalless draw on their SPL debut and lost 3-2 at Fir Park in December. Given Adams' change is approach, the game looks more likely to replicate the first one. Adams said: "Probably midway through the season we went to try to win a few matches and opened up a bit, and it didn't really suit us. We have got back to what we are good at - being solid, playing on the counter-attack and keeping good possession in the middle of the park. We looked at it and looked at the players we have got, and they are suited to a system. I think the signings over the transfer window have helped us as well." County can move from ninth place into the top six if they beat Motherwell and allow thoughts of ending the season with a European place. Adams argues that the competitive nature of the race for Europe shows that plans to reform the league structure are misguided. SPL and SFL clubs are due to vote on plans to split the top two divisions into three groups of eight after 22 games. Adams said: "We wouldn't be in this situation if it was the new structure that they are looking to take into place. We would be playing in the bottom half with First Division sides. I think it's great that the structure we have in the SPL at this stage of the season where the 11th team can look to try to get into Europe. St Mirren are only eight points off Hibs. I think they are wrong to change the structure of the game for a few clubs. The fans were very adamant that they wanted the league to be competitive and they have certainly had that. We don't know who is going to finish in the top six or finish in the European places. We have only got 11 games to go. That's something the fans wanted at the start of the season and they are going to get it all changed probably for next season."
