Chelsea could be on the verge of making their fourth signing of the January window, with Italian sources claiming that Hajduk Split midfielder Mario Pasalic has flown to London to seal a move to Stamford Bridge.

The Croatian Pasalic, 18, has caught the eye this season with a number of mature performances, and has six goals from 13 appearances this season for Hadjuk.

The midfielder has flown to London with the Hajduk club president, according to Gianlucadimarzio.com, and he is set to follow Traore, Matic and Salah in moving to Stamford Bridge this month.

The report stated that Serie A side Lazio had previously showed an interest in Pasalic, but following the news that the Croat has taken a trip to London, the chances of him making a move to Italy are now very slim.
