Former England goalkeeper Gordon Banks says Manchester United manager Sir Alex Ferguson must be regretting not signing Manchester City No.1 Joe Hart.
The 25-year-old has established himself as one of the finest 'keepers in the world since moving to the Etihad Stadium from Shrewsbury six years ago for a fee of just £100,000.
Manchester United, meanwhile, have struggled to find a capable and consistent replacement for Old Trafford legend Edwin van der Sar since he retired last year, with Ferguson choosing to chop and change between David de Gea and Anders Lindegaard.
De Gea arrived at Manchester United in the summer transfer window of 2011 as a £17 million acquisition from Atletico Madrid, but has struggled to establish himself as Ferguson's No.1 gloveman.
Lindegaard, meanwhile, was initially recruited as back-up for Van der Sar and has been required more often than originally expected given De Gea's issues since his move to United.
According to Banks - a World Cup winner with England in 1966 - however, Manchester United boss Ferguson would have no such trouble had he moved to secure a deal for Hart before Manchester City managed to do so.
“I am not sure about the two keepers at United, not at all,” he told the Daily Express.
“Sir Alex Ferguson could have got a better keeper than either of them.
“I am sure he wishes he had signed Joe, who is the best English goalkeeper by a mile and could become the best in the world.
"He is now making terrific saves for Manchester City, while these lads at United look as if they can let in important goals."
Banks, meanwhile, believes Hart has the potential to become the best goalkeeper in the world, but the Manchester City man is currently behind Real Madrid captain Iker Casillas in the rankings.
“Can Joe be the best in the world? I don’t think he is there yet – I rate Iker Casillas at Real Madrid – but considering the age he is, he stands a great chance of becoming the best," he added.
“He is the best English goalkeeper by a mile, no question, and there is every chance he will surpass Peter Shilton’s 125-cap record because he is only 25."
