Chelsea boss Tuchel urges Werner to keep improvingChelsea's German striker Timo Werner (R)LONDON - Thomas Tuchel warned Timo Werner he must keep improving after the Chelsea striker's first Premier League goal since April helped seal a 3-1 win against 10-man Southampton on Saturday. Werner saved Chelsea from a frustrating end to a difficult week when he netted six minutes from full-time at Stamford Bridge. For a player who has had a remarkable 16 goals disallowed since he joined Chelsea, Werner will surely benefit from the jolt of confidence that will follow his second club goal of the season. Chalobah, Chilwell and Ruben Loftus-Cheek all added energy and enthusiasm to a Chelsea team that had looked stale in their previous two games. At a club like Chelsea you need to be sharp every few days and fight for your place."
