Shearer told The Sun: “Just when Tevez was at the centre of all that controversy at the end of last season, he started scoring goals left, right and centre and kept West Ham up almost single- handedly and against all odds.
“That suggests he will not have been affected by all the uncertainty over his future this summer and that he will be a success at United.
“Tevez is just the sort of exciting talent Sir Alex has always liked to sign. He has really had to go out on a limb to sign Tevez and he wouldn’t have gone through all this if he didn’t rate him very highly.
“I don’t believe Tevez and Wayne Rooney are too similar — because great players can always play well together.
“It was said that Chris Sutton and me were too similar at Blackburn but we won the title.
“OK, Rooney and Tevez do not have a lot of height but that is not the way Manchester United play. How often do you see them aiming high balls up front? Not very.
“Man United will be an even more exciting, entertaining team with Tevez in the side and you wouldn’t bet against them winning the title.”
