Chelsea coach Enzo Maresca has urged goalkeeper Robert Sanchez to improve after costly errors contributed to their 3-1 Premier League defeat to Manchester City, intensifying speculation about the club seeking a new goalkeeper in the January transfer window.

Enzo Maresca insists he continues to ‘trust’ Robert Sanchez despite the goalkeeper’s mistake in Chelsea ’s 3-1 defeat to Manchester City on Saturday. Chelsea took an early lead as Nicolas Jackson capitalised on an error from City’s new £33.6 million signing Abdukodir Khusanov to give Noni Madueke a simple tap-in from close range.

Chelsea are sticking by goalkeeper Robert Sanchez for the season, but targets are being looked at for the summer transfer window.
