Manchester United boss Sir Alex Ferguson doesn't see any major new threat from the top four this season.

He said: "None of us (United, Chelsea, Liverpool, Arsenal) have really gone into the market in a big way.

"We have sold Ronaldo, Liverpool have sold Alonso, Arsenal have sold Adebayor. It has been really quiet in terms of the big four.

"John Terry staying will keep Chelsea stronger. He is a good centre half, no question.

"We will cope without Cristiano. For any player, whether it is Wayne Rooney or (Federico) Macheda or (Danny) Welbeck or Nani - all the forwards - they all have to say, 'Well, this guy was exceptional'. And the only way that any player can achieve an improvement is by practice on the training field.

"People in our game mis-read what a training session means. It is not just to fill your morning. It is to improve yourselves as footballers and we are lucky that some of the players we have here at the moment have that desire to improve."
