Harry Redknapp admits Tottenham’s threadbare squad will be tested to the full before he can look forward to a return to Wembley.

Redknapp enjoyed the first taste of Wembley success in his long career when he led Portsmouth to FA Cup final victory over Cardiff last season and he is on the verge of another trip to the English national stadium.

Now in charge at Tottenham, Redknapp will be walking out at Wembley again on March 1 if his new side can overcome Burnley in the League Cup semi-finals.

Tottenham, who beat Chelsea in last season’s final, can take a giant step towards defending the trophy with a victory over the Championship club in the first leg at White Hart Lane on Tuesday.

But Redknapp fears a hectic schedule of four games in 12 days could stretch his injured-ravaged squad to breaking point.

Such is the severity of the injury crisis that Redknapp has been forced to call up that players who weren’t even given squad numbers at the start of the season.
