Former Tottenham boss David Pleat believes Chelsea's hopes at Manchester United tomorrow will depend on John Obi Mikel.
Pleat says the Nigeria midfielder needs to play the game of his life at Old Trafford.
He wrote in his column for the Guardian: "It is how Chelsea, and Mikel John Obi, react to that threat that could be key in this game.
"Mikel is vital as he plays with his head as well as his heart. He must not chase the ball. He must keep Rooney in sight. He must deter him by fair means in the tackle. He must not be drawn too wide and, most importantly of all, must not be drawn too deep. Discipline is so vital in this role. If the visitors are to become the first side to prevail at United this season, Mikel must play the Claude Makelele role better than the man himself."
