Chelsea are a club in trouble. That’s the vibe if you believe The Sun today, who say that the Blues are worried over the long-term repercussions their poor season might have. Apparently the powers that be are fretting over the possibility of not qualifying for the Champions League and are worried about the shaky stance of the dressing room. To cap off the fears they believe such woes could see the likes of Diego Costa, Eden Hazard, Thibaut Courtois and Oscar leave. In any case, they’ll have a fight to keep them without Europe’s premier competition. Meanwhile, David Luiz has looked to stoke the fires of speculation for one of those players, by suggesting Costa would be welcome at Paris Saint-Germain. Luiz said Costa was one of the most clinical strikers in Europe - no argument from us.
