BBC Sport explains why the January transfer deadline is in February, and how that compares to other European leagues.

A very good Friday morning to you and welcome to our live coverage of football’s January transfer window. This is the sole mid-season period where clubs can buy and sell players to deal with their injury issues, repair summer mistakes or find solutions for a new head coach.

There's shades of the Randal Kolo Muani deal here, with Manchester United realising the same thing PSG did: The only way to stand any chance of one day recouping a decent fee for an unwanted player is to get him out on loan and playing first, in order to rebuild his confidence. But it's quite a turnaround from his €95m arrival.

Jutta Rantala and Lena Petermann – the club's two top scorers last season – are both currently sidelined, as is French striker Noemie Mouchon after repturing her ACL in October. Eiriksdottir may be able to fill the void left in Leicester's front line.
