Paul Merson says Chelsea manager Thomas Tuchel 'shot himself in the foot' by leaving out 'phenomenal' Mason Mount during last weekend's shock loss to West Brom.
In-form Mount didn't start the game at Stamford Bridge and though he replaced Christian Pulisic at half-time, the England midfielder wasn't able to avert a damaging 5-2 defeat.
Mount, 22, then issued a reminder of his class by scoring his eighth goal of the season in Chelsea's midweek Champions League win over Porto.
Former Arsenal and Aston Villa forward Merson believes Tuchel made the wrong call by leaving Mount out against relegation-threatened opponents and claimed the German manager underestimated the strength of the Premier League.
