Lionel Messi: Manchester United boss Sir Alex Ferguson will regret getting rid of Carlos Tevez

Man on a mission: Tevez has been in sensational form for City this season since leaving United 

Lionel Messi believes Sir Alex Ferguson made a huge mistake by letting Carlos Tevez leave last season and reckons it could come back to haunt him at this weekend's Manchester derby.

Manchester United boss Ferguson refused to splash out the £25.5million agreed fee on Tevez, who spent two years at Old Trafford on loan, so the Argentina striker moved to the blue half of city.

Tevez has repaid Manchester City's faith in him by scoring 28 goals in all competitions for his new club including strikes against United in both legs of the Carling Cup semi-finals ahead of the Barclays Premier League derby at Eastlands on Saturday.

Messi, FIFA World Player of the Year and Argentina team-mate of Tevez, says Ferguson should have 'valued' the Buenos Aires-born striker more when he was at Old Trafford, reports The Daily Express.

And Barcelona forward Messi said: 'I have learnt a lot from Carlos. He has proved this season he is one of the best strikers in the world and Manchester United have shown just how much they have missed him. He needed to be somewhere he was valued. He is such a nice guy, he must be with a club who really want him and respect him.
