Tottenham Hotspur are investigating whether criticism of the Premier League club's chairman on Darren Bent's Twitter page were posted by the England forward, a spokesman for the club said Friday.

The comments on the social networking website included an expletive aimed at chairman Daniel Levy amid a rant about Bent's frustrations over the drawn-out negotiations surrounding his possible transfer to fellow Premier League side Sunderland.

Do I wanna go Hull City? NO. Do I wanna go Stoke? NO. Do I wanna go Sunderland? YES, Bent's 'tweeter' page said after he was also linked in media with Hull and Stoke City.

A Spurs spokesman said investigations into the Tweeter comments were underway but had not yet been completed.

It's still being looked into. We don't have answers yet When we do the matter will be dealt with internally. It's just a case of finding out whether it actually is his page or not.

Sunderland manager Steve Bruce told Sky Sports News the failure to agree on a transfer fee was the main stumbling block to agreeing a deal for Bent to join the north-east club.

Only 24, 48 hours ago we thought we were virtually there. Obviously, other clubs have shown an interest.

We're hopeful that we can still try and do a deal if we possibly can... we will obviously pick up discussions in the next two, three days and see what it takes, Bruce said.
