There are no doubts in Charlie Adam mind ahead of Scotland meeting Wales in Cardiff on Friday. He can only see a Scotland win as the result as Craig Levein's men hope to improve on their opening two draws in the World Cup qualifying group. Many pundits see a win for Scotland as the only result that can allow realistic hopes of qualifying for Brazil to remain. The Stoke midfielder, though, is not minded to accept the doomsday scenario of defeat in Cardiff. He said: "There is no point thinking that we are not going to win. That's the problem these days, everyone has a doubt. Let's be positive, let's try to get behind the team, like the Scotland fans try to do, and try to get the three points because this could be the start of something on the road to Brazil and hopefully we can continue that on Tuesday night against Belgium." The former Liverpool, Blackpool and Rangers player does not believe anything he ears about the Welsh camp supposedly being in turmoil as they approach their make-or-break double header against Scotland and Croatia. Wales took a 6-1 beating from Serbia after a 2-0 home defeat to Belgium in their Group A opener. Under-fire manager Chris Coleman, who has lost all four games since taking over from the late Gary Speed, subsequently took the captaincy away from 21-year-old Arsenal midfielder Aaron Ramsey and gave it to Swansea defender Ashley Williams. However, Adam said: "Are they in turmoil really? I don't think they are. They have good players. Results are difficult at this level. The games they have had have been tough games. They were beaten by Belgium and away in Serbia which is a tough place to go. It was surprise that they took the captaincy off him (Ramsay) but the manager saw fit to change and you have to respect that decision Whatever happens in the Wales camp happens there. For us, it's about concentrating on ourselves and looking forward to the next game. We go there with confidence, we have got good players in our team and hopefully we can perform and try to get three points."
