Chelsea have reportedly made a fresh £15m offer for Atletico Madrid left-back Filipe Luis.
The Brazilian is widely regarded as one of the best full-backs in European football, with his performances last season helping Atletico claim their first La Liga title since 1996.
However, Chelsea have been strongly linked with a move over the last couple of months, with Luis also believed to be keen on a transfer to London.
According to The Times, Chelsea have made a new £15m offer, but it is understood that Atletico are still looking for closer to £20m.
Atletico have already lost Diego Costa to Chelsea this summer.
