Timo Werner and Kai Havertz's struggles at Chelsea are "normal", according to Manchester City star Ilkay Gundogan, who has backed the Blues duo to come good at Stamford Bridge after a tough start to life in England.
Chelsea forked out a combined total of £117.5 million ($161m) to bring Werner and Havertz to west London in the summer transfer window.
Werner had terrorised defences in both the Bundesliga and Champions League at RB Leipzig, establishing himself as one of the most exciting young strikers in Europe in the process.
