Olivier Giroud (left) sits next to striker partner Alvaro Morata (right)After the summer signing of Alexandre Lacazette, Giroud only started one league game under Arsene Wenger this term, and the arrival of Dortmund forward Pierre-Emerick Aubameyang last month saw Giroud seek a move elsewhere after nearly six years at the club. Giroud landed a move to the reigning champions, where big-money summer signing Morata had been misfiring before suffering a back injury at the end of last month. Michy Batshuayi has joined Borussia Dortmund on loan form Chelsea until the end of the seasonBut what does Giroud offer Chelsea and how does he differ from Morata? In addition to scoring headed goals, Giroud is prolific with his favoured left bootUltimately, Giroud is more effective at converting big chances. This season, Morata has missed 0.8 big chances per game, compared with Giroud's 0.2 last season.
