Arsenal legend Ian Wright fears more players will follow Robin van Persie out the exit door.

Van Persie is expected to be confirmed a Manchester United player today.

Wright wrote in The Sun: "It is a massive shame that the Dutchman is becoming the latest star to leave Arsenal, though I am not surprised. If Arsenal supporters are being honest with themselves, they will not be too shocked either. It is the sign of the times.

"The three teams who always look capable of winning things these days are United, Manchester City and Chelsea.

"United won nothing last season and some people claim Alex Ferguson's side was one of the poorer teams from his time in charge.

"Yet still they only lost the league title on goal difference in the last couple of minutes of the campaign.

"They will still take some beating in 2012-13 and it is extremely rare for United ever to go more than one season without managing to win at least one trophy.

"I hate to see top performers leaving the Emirates and it will now become increasingly difficult for the club to keep their other star names."
