Chelsea have made a shock enquiry for Saido Berahino, Football Insider sources understand.

The Premier League champions have made a move for the West Brom striker as they assess the possibility of a January deal.

Newcastle and long-term admirers Tottenham are also keen on landing Berahino, who has made it clear that he wants to leave the Hawthorns.

West Brom manager Tony Pulis admitted last week that the club would be willing to sell Berahino for the right price.

A Chelsea source has told Football Insider that the 22-year-old is on the club’s radar as they bid to provide forward back-up to Diego Costa.

The Spain international is the undisputed first choice at Stamford Bridge, but, the only other options Radamel Falcao, who is out until March with a hamstring injury, and Loic Remy have scored only four goals between them this season.

Costa is in a race against time to be fit for Sunday’s Premier League showdown against Arsenal after suffering heavy bruising to his shin in the 3-3 draw with Everton last Saturday.

Newcastle are keen to bring Berahino to St James’ Park as the fourth-bottom side attempt to bolster their squad in their bid to avoid relegation.

Owner Mike Ashley has already brought in Henri Saivet from Bordeaux and Jonjo Shelvey from relegation rivals Swansea since the January transfer window opened.

Meanwhile, Spurs boss Mauricio Pochettino still regards regards Berahino highly even though he has scored just three league goals this season, and only six in total.

West Brom could be tempted to sell Berahino this window as he only has 18 months remaining on his contract at the Hawthorns and Pulis has questioned the player’s attitude on a number of occasions.
