Graeme Souness believes Wayne Rooney is yet to reach his peak at Manchester United.
Rooney struck his 200th goal as he hit a brace for United against German outfit Bayer Leverkusen last night.
Rooney had continuously been linked with a move away from Old Trafford over the summer but is now closing in on Sir Bobby Charlton’s all-time record of 249 goals for the Red Devils and Souness expects the England international to get even better in seasons to come.
Speaking on Sky Sports, he said: "Logically, Rooney should just be reaching his peak.
"In the next three years he should be at his very best.
"Last year he wasn't playing - Fergie, for whatever reason, decided not to use him and he wasn't involved in some big games at all.
"He's gone from being first pick to third or fourth choice - whether it be up front or somewhere in an attacking formation in midfield.
Souness also believes Rooney can thrive under new boss David Moyes and believes the strikers mentality will continue his success at United.
He continued by saying: "I think he had his nose put out of joint and I think under this new manager he feels loved again. It's a simple case of him wanting to play football.
"If the stories are correct - and you can imagine it when you see him playing football - he's first on the training ground and you have to drag him off it.
"When he's fully at it you can see that enthusiasm in spades. He's a bit like Carlos Tevez and Sergio Aguero in as much as he makes other people play with his enthusiasm."
Rooney’s double last night helped United on their way to a 4-2 opening Champions League group game victory over Leverkusen.
Robin van Persie and Antonio Valencia also struck for Moyes’ side, who now turn their attention to the Manchester derby on Sunday.
