Carlos Vela admits that performing well at the World Cup could 'open many doors' - although he is not thinking of his club future just yet.[LNB] The Arsenal forward has shown glimpses of his talent at Emirates Stadium, including a sublime goal against Fulham on the final day of the Premier League season.[LNB]But he has had few opportunities to impress and, despite signing a new long-term contract in December, appears to have fallen further down the pecking order after Marouane Chamakh was signed from Bordeaux.[LNB]Vela concedes that it was a frustrating campaign for him personally but he is now raring to go ahead of the World Cup in South Africa.[LNB]And the 21-year-old is fully aware that he could press his claims for more regular inclusion at Arsenal with a good tournament or even attract interest from elsewhere.[LNB]"It was difficult. I didn't have many chances when I was fit," Vela said in The Sun.[LNB]"Then, injuries didn't allow me to be in good form. But I still have time to get ready for the World Cup.[LNB]"I'm only concentrating on playing for Mexico and having a good World Cup. [LNB]"Having a good World Cup can open many doors. If not at Arsenal, we'll see where."[LNB]One player who could be leaving the Gunners this summer is Cesc Fabregas, with the Spanish midfielder having reportedly told club bosses that he is keen to join Barcelona.[LNB]Barca have yet to make a formal offer but Vela can understand why his team-mate would want to return home after an unsuccessful stint with Arsenal in terms of silverware.[LNB]"He will be going back to his country and it is good for him," Vela said in the Daily Express.[LNB]"It is difficult for big players, they want to win trophies and play in games like the Champions League final. I'm sure he's disappointed we have not won anything for five years.[LNB]"Of course it will be sad to see Cesc join Barcelona. He is the star of the Arsenal team and it is better to have him. But it is a decision for Cesc."[LNB]Turning his attention back to Mexico, Vela voiced his satisfaction with the performance against England at Wembley on Monday night.[LNB]Fabio Capello's men eventually ran out 3-1 winners but Mexico impressed with their fluent football and Vela was surprised by how many chances his team were able to create.[LNB]"It was very strange. Normally England are very strong in defence," he said.[LNB]"Mexico played some fantastic football in the first half. Unfortunately, England have some fantastic players and they were very dangerous."[LNB]Looking ahead to the next few weeks, Vela added: "I'm very excited. It is a dream to play in the World Cup. It is what you work towards every day."
