Chelsea to bid £15m for Bayern Munich's Luiz Gustavo?

Chelsea are reportedly tracking Bayern Munich's Brazilian international Luiz Gustavo.

Blues boss Jose Mourinho is keen to add a holding midfielder to his squad and is preparing a £15m bid for the Champions League winner, according to The People.

The move would pave the way for John Obi Mikel to leave the club amid reported interest from Turkish side Galatasaray.

Gustavo was part of the Brazil side that won the Confederations Cup last month.
