Watford goalkeeper Manuel Almunia isn't surprised Robin van Persie quit Arsenal for Manchester United.

Almunia, who joined the Gunners from Celta Vigo in 2004, believes Van Persie moved to Manchester United because Arsenal lacked ambition in the transfer market.

"I think Robin saw that Arsenal didn't sign players as good as he wanted them to be this summer," he told the London Evening Standard. "I know him well and he always wanted to win, he had been at Arsenal for a long time without winning and that was another main factor.

"But life goes on. People choose their way in life and Robin chose to leave. I wish him luck because he deserves everything good that happens to him."
