Damien Comolli is under huge pressure at Tottenham to keep his sporting director's post, it has been revealed.

The Times says the Frenchman has this summer's transfer window to recoup some of the substantial amount of money that the club have spent, under his direction, on players in recent seasons or risk being sacked in the autumn after three years in his post.

Comolli's tenure has come under scrutiny in part because of the estimated fall in the value of some of his expensive acquisitions and some disagreements with Juande Ramos, the Tottenham head coach. Darren Bent, Younes Kaboul, Ricardo Rocha and Kevin-Prince Boateng cost a combined fee of about £32million in the past 18 months, but they are now arguably worth half that sum. This has led to questions about whether Comolli is delivering value for money.

Tottenham would not want to disrupt their transfer strategy this summer by dismissing Comolli now. Daniel Levy, the chairman, has shown that he is willing to give his staff an opportunity to turn things around.

There is no suggestion that the club will discard their continental structure, brought in by Levy.
