Porto left-back Aly Cissokho is a target for Tottenham boss Harry Redknapp.

The Sun says Redknapp has been keeping tabs on the French defender for some time.

Cissokho, 21, was impressive in Porto's 2-2 draw against Manchester United on Tuesday and now Redknapp is ready to make a summer bid.

The player joined Porto in January and looks a bargain at the £270,000 paid to Vitoria Setubal.

Porto will fight tooth and nail to keep him which means Redknapp will have to cough up at least £5m.
