Tottenham are understood to have made a £3.5million bid to sign Manchester City winger Martin Petrov. Spurs had been interested in the Bulgaria international for a few seasons but lost out to City in 2007 after not being able to offer him the same wages.

He is believed to be on £70,000 a week but is now only a fringe member of the squad at Eastlands following their mass spending in the transfer market.

Harry Redknapp sees Petrov as providing good width on the left flank and signing him would give the Spurs manager the option of moving Luka Modric into a more central role.

City are prepared to do business but will probably hold out for a higher fee before the window closes on Tuesday.

Spurs have already been involved in the transfer market today by agreeing to sell White Hart Lane misfit Kevin-Prince Boateng to Portsmouth for £4m. They are set to loan Jamie O'Hara to the struggling Premier League club.

Pompey have been taken over by Arab tycoon Sulaiman Al Fahim and manager Paul Hart is keen to spend his cash before the transfer deadline.

Boateng, 22, has played only 14 times for Spurs since his £5.5m move from Hertha Berlin two years ago, including Wednesday's Carling Cup win at Doncaster, where the German Under-21 international's first contribution was to concede a penalty.

Redknapp said: "I believe the sale is for £4m. He hasn't played much but he cost a lot in the first place."

O'Hara's departure, however, is only to get more first-team action as Modric is keeping him out of the side.

Redknapp said: "Jamie is a terrific young player who needs to play games so we're prepared to let him go out on loan until Christmas. Certainly they would be getting an excellent player. If they can sort something out then I would let him go for a couple of months."
