The Ajax captain will be lining up against Sir Alex Ferguson’s side in the second leg of their Europa League last 32 tie and the Spurs boss sees it as the perfect opportunity to kill two birds with one stone.
Spurs and United meet a week on Sunday but Goal.com are reporting that his primary mission at the Red Devils’ game is to size up Vertonghen ahead of a potential £10million summer offer.
The report claims that United themselves are interested in the services of the Belgium international, whose contract runs out in the summer of 2013 and he does not look likely to sign a new one.
Redknapp is the odds-on favourite to take over the England job but he has still been working towards identify possible targets for the White Hart Lane club next season, according to the report.
Tottenham reportedly see Vertonghen as the perfect long-term replacement foe Ledley King – the Spurs club captain is nearing the end of his career and it is unknown for how long he can continue to play as regularly as he has by managing his injuries.
