LONDON, Jan 4 (Reuters) - Chelsea handed London rivals Arsenal a welcome boost in ‌the Premier League title race as Enzo Fernandez struck a stoppage-time equaliser that prevented Manchester City closing the gap at the top to four points on Sunday.

City led through a Tijjani ‌Reijnders goal in the first half and it looked like being enough for them to cut into Arsenal's lead at the summit, but Fernandez pounced to give Chelsea a ‌worthy 1-1 draw, three days after the club sacked coach Enzo Maresca.
