Striker
Olivier Giroud – Has many critics and some of them are his own supporters, but by scoring 16 league goals last term the France international proved he does offer something to the team and remains the only out-and-out striker at the club in form – 6/10.
Diego Costa – In what has been a heavy period of spending for Mourinho this former Atletico forward is his most expensive purchase at £32m and if can emulate last year and net 36 goals that will seem worth it – 7/10.
Total
Arsenal – 77/110.
Chelsea – 82/110.
