Manchester United manager Sir Alex Ferguson has insisted that he needs to keep improving his team despite winning the Premier League title with four games remaining.
United sealed the title with victory over Aston Villa on Monday evening, but despite the Old Trafford outfit sitting 16 points clear of Manchester City, Ferguson has signalled his intent to make additions to his squad during the summer.
The 71-year-old told Sky Sports News: "Having spoken with the Glazer family, there is every intention to kick on.
"We possibly need two players. It depends. If a player came along who met our criteria we would push the boat out and get him, irrespective of how many players we have."
Ferguson has been linked with a move for Borussia Dortmund forward Robert Lewandowski.
