The best/worst case scenarios for SIX Chelsea players this season

Diego Costa

Best case: Costa regains the form he showed in Madrid last year, leading the Chelsea attack and becoming one of the top strikers in the Premier League alongside Wayne Rooney and (if he stays at Liverpool) Luis Suarez. The 25-year-old proves he’s worth every penny of the £32m Mourinho paid and is one of the top signings of the offseason.

Worst case: Costa struggles to find his footing in the more physical Premier League, proving the skeptics right that he should have stayed in La Liga. Finding the right chemistry with Eden Hazard, Oscar and Cesc Fabregas proves difficult, and Costa eventually loses his starting spot after Mourinho buys a replacement striker in the January transfer period.
