Ben Foster has now played as many games at Wembley in 2009 as he has at Old Trafford - but the England goalkeeper admits any match is a bonus.The 25-year-old has been restricted at Manchester United due to the form of Edwin van der Sar but is thought of highly enough for Fabio Capello to use him in the second half of the friendly win over Slovakia.It meant a return to the national stadium for Foster after starring in United's Carling Cup triumph a month ago."It was a great occasion for me," Foster told the FA website. "Any game I play this season has been a bonus, there haven't been that many coming my way."The fact that I've played two games at Wembley, one for my country and one in a cup final, is fantastic for me this season."It was a bit out of the blue to get called up and then to play some part in the game as well."It was a great performance and result, and I was glad to be part of it."Foster has recovered from a serious knee injury and his appearance against Slovakia came two years after his debut."You can't lose belief, I've had a few injuries but once you are back to full fitness you want to push into your team and then England," he added. "I thought I would get that."Foster feels he needs to be playing every week to retain his place in Capello's squad and stand a chance of travelling to the World Cup next year."It's a nice feeling just to be involved," he said. "I need to be playing football now, regular first-team football is a must. It's going to be a big season for me next year."Wayne Rooney, Foster's United team-mate, scored twice during the 4-0 win and Foster added: "He was fantastic, from the first minute he was putting so much hard work in."
