Chelsea's preparations for the derby with West Ham have been disrupted after a canceled flight from Greece.

The Sun says Chelsea have been forced to stay in Greece for an extra night after their flight home was cancelled due to bad weather.

And the overnight delay has put a spanner in the works for their preparation plans ahead of Sunday's clash with West Ham.

Chelsea were planning on returning back from their 1-0 Europa League win over PAOK on Thursday night.

But they instead had to stay another night at the Hyatt Regency Hotel in Thessaloniki and are now due back in London this afternoon.
