Chelsea were probably busier in the January transfer window than most fans realise.
While the Blues did not make any high-profile transfers, they completed many incoming and outgoing deals.
Liam Rosenior’s side confirmed 10 moves on deadline day, several of which involved sister club Strasbourg.
The Chelsea Chronicle looks at every transfer that the Blues made in the January window.

Chelsea incomings on transfer deadline day
Mamadou Sarr (Recalled from Strasbourg)
Chelsea’s only incoming deal on deadline day was Mamadou Sarr’s return from his loan spell at Strasbourg.
Sarr performed well under Rosenior at the Ligue 1 club, so he could have an immediate impact at Stamford Bridge.
