Chelsea are expected to be one of the busiest Premier League clubs during the January transfer window.
The Blues want to bolster their squad to secure Champions League football for next season. Although they are currently inside the top four, Arsenal are just three points behind Maurizio Sarri's side with a resurgent Manchester United a further three back.
And while Cesc Fàbregas, Callum Hudson-Odoi and Álvaro Morata all look to be heading for the Stamford Bridge exit door, high-profile arrivals are also expected.
Chelsea have this week been linked with highly rated Cagliari midfielder Nicolò Barella, who seems to be a readymade replacement for Fàbregas.
The 21-year-old is likely to cost £45million and while that is certainly a significant outlay for a player of his age, he is one of the most sought-after talents in Italy for good reason.
In this video, we take a closer look at Barella and examine how Chelsea may line-up after his arrival.
