Former Bayern Munich star Mario Basler admits Jamie Gittens has it all to prove at Chelsea this season.
While rating the potential of Gittens very highly, Basler insists he left Borussia Dortmund over the summer with major doubts about whether he can succeed at a major club of BVB's level.
Indeed, Basler insists Dortmund were far better in the final weeks of the season when coach Niko Kovac decided to bench Gittens.
