Sevilla forward Alvaro Negredo is believed to be back on Tottenham's radar after a injury scare to in-form striker Jermain Defoe.

The England striker, who is just one of two senior forwards at the club along with Emmanuel Adebayor, is currently nursing a pelvic injury which kept him out of the FA Cup clash against Leeds on Sunday.

According to the Mail, Spanish club Sevilla are willing to let Negredo go for approximately £15 million, a price tag not likely to scare Tottenham off as they attempt to strengthen their attack in their bid for a Champions League spot.

With Adebaoyr away on national duties in the African Cup of Nations, the North Londoners were forced to field Clint Dempsey as a makeshift forward after the injury to Defoe.

However, Defoe is struggling with a pelvic injury and has been playing with discomfort for quite some time. After a blazing start to the season his form has declined and he has scored only once in his last eight games.

Tottenham manager Andre Villas-Boas said after his club's FA Cup defeat to Leeds that Defoe, who has netted 16 times this season, was expected to feature against Norwich on Wednesday with the striker being given an injection in the hope of being fit. However, as the injury nags away the fear of an operation looms.

Spurs have long been in the market for a striker, with 27-year-old Negredo now emerging as the main transfer target along with Brazilian long-term prospect Leandro Damiao and Aston Villa's Christian Benteke - the latter enjoying an impressive debut season in England having scored 11 times for Villa.

Negredo has scored 14 goals in all competitions this season and was once again on the scoresheet on Monday night as Sevilla secured a 3-1 win over Granada.

Meanwhile the club yesterday completed the singing of German attacking midfielder Lewis Holtby on a four-and-half-year deal. The 22-year-old has been given the number 23 shirt and will be hoping to make an instant impact after deciding to leave Schalke.
