Manchester United manager Sir Alex Ferguson has hailed an improvement in concentration by central defender Rio Ferdinand as one of the main reasons for his side's superb form.
The 28-year-old England stopper has often been criticised for losing concentration at key moments, but Ferguson has detected an improvement by Ferdinand - who has benefited from the presence of Nemanja Vidic alongside him.
Ferguson said: "I don't think there is any doubt he has always had a fantastic talent, with balance and use of the ball.
"His technique for a centre-back is probably the best in the game.
"The area in which he has improved in is his concentration.
"He and Nemanja Vidic have formed a good partnership and it will get better because they are young.
"I think I rested him for one game and I don't think the number of games will affect him. He is a strong athlete and I have been delighted with him."
