Tottenham have stepped up their interest in Toulouse striker Wissam Ben Yedder this January with uncertainty over the signing of Saido Berahino in the current transfer window. Yidder has been in prolific form this season, scoring 12 goals in only 21 appearances for the relegation threatened club and would make for some good business for Mauricio Pochettino's men, who are looking to challenge for a place in the top four.

The Mirror reports that the striker is likely to be available for a fee in the range of £7.5m ($11m), a pittance compared to the £25m valuation that West Bromwich Albion have slapped on Berahino. Yidder is also in much better form compared to Berahino this season, with the Frenchman scoring seven goals in his last five appearances, compared to the Englishman, who has been on the fringes.

Berahino has managed only four goals in 18 appearances, coming off the bench on most occasions after his altercation with the management over a summer transfer. Chelsea have emerged as a surprise candidate for a move in January, with the Blues having identified Berahino as back-up for Diego Costa.

Yidder, who has only a year and a half left in his current contract, is looking to save Toulouse from relegation, with the Ligue 1 club's president desperate to hold on to him until at least the end of the season. "Wissan is a fantastic boy who will leave in June," club president Olivier Sadran said in an interview. "He will go in conditions that are attractive to him. More interesting than today, more choices and financially better. We have to keep him."

Pochettino is desperately looking for a back-up for Harry Kane, who has played almost every game thus far for Spurs in all competitions, but his research thus far has failed to yield any results. The north London club are currently in fourth spot, only five points adrift of leaders Arsenal and are ready to move for the title after consolidating their position in the top four.
