Wales captain Aaron Ramsey knows his side must put their disappointing start to World Cup qualifying behind them and get back on track against Serbia tonight.

Wales opened their bid to reach the 2014 finals in Brazil with a 2-0 defeat at the hands of Belgium at the Cardiff City Stadium on Friday night.

Belgium are viewed as one of the favourites to top Group A but Wales were left aggrieved by a handful of key decisions that went against them.

In particular, manager Chris Coleman criticised the first-half sending off of James Collins while the score was 0-0, and the decision to penalise Ramsey for the free-kick from which Jan Vertonghen struck Belgium's second.

Like his manager, Ramsey believes there were plenty of positives to take from the game, but wants any sense of grievance to be put to one side at the Karadjordje Stadium.

The Arsenal ace said: "We are delighted with how we defended and counter-attacked against Belgium and it was a shame we couldn't get a couple of goals, but it is always difficult when you are down to 10 men against a good side.

"But that game has gone now, we can't dwell on what's happened.

"We have to move on from it, we felt a couple of decisions went against us like when they scored off the free-kick, but we can't do a lot about it.

"I felt we played well, we defended well and hopefully we can do that tomorrow and play with 11 men for the entire game and have a better opportunity to get a result.

"It will be an interesting battle and hopefully one we can come out on top."
