LONDON, ‌Jan 31 (Reuters) - Chelsea battled from two goals down to beat West Ham 3-2 ‌in the Premier League on Saturday with a stoppage-time Enzo Fernandez winner crowning ‌the second comeback win in four days for the Blues under new coach Liam Rosenior.

The Hammers, struggling in the relegation zone, took full advantage of a careless Chelsea performance in the first half, possibly a result of ‍tiredness after the Blues came from behind to beat Napoli ‍3-2 in the Champions League on ‌Wednesday.
