Thomas Tuchel believes that Chelsea's style of play sometimes holds Timo Werner back as the possession-hungry side cause opponents to sit in defensive shapes.
Chelsea have averaged 69 per cent possession in the six league games since Tuchel has taken over, which has caused their rivals to sit deep and hit them on the counterattack.
Werner has scored just once in the eight matches since Tuchel came in. Although the forward has shown signs of improvement, the Blues will demand more from their £47.5 million signing from RB Leipzig.
