Keep Eden Hazard quiet
If Diego Costa is missing through injury, then Chelsea’s threat is depleted. However, in Eden Hazard, they have one of the best players in the world currently. If we can keep the Belgian quiet, then Jose Mourinho’s men will have lost their main outlet, the one man in their side that can makes things happen out of less than nothing, in a similar way that Philippe Coutinho does for us.
Sticking Emre Can at right-back, and leaving him to deal with Hazard alone, may be a risk that comes back to punish us. However, the German has enough ability to halt his creativity. Perhaps, it would make sense to give one of the defenders the freedom to monitor the pair, and offer help if required.
