Nothing has better summarised the inconsistencies in Chelsea's attack this season than the past month. Heading into the final international break of the campaign, it appeared that Christian Pulisic and Hakim Ziyech were the names Thomas Tuchel would pick alongside the trusted duo of Kai Havertz and Mason Mount.
Pulisic had scored important goals against Lille to get the Blues into the last eight of the Champions League, and Ziyech was providing a more consistent streak of inspiration many had waited for since his signing in 2020. Timo Werner was firmly at the back of the queue, even more pinpointed by his display in the defeat to Brentford.
But flash forward to Sunday against West Ham where Timo Werner was a starter, Pulisic and Ziyech watching on from the sidelines, neither had started a game since the first leg against Real Madrid. Both came off the bench and impressed, but it was the American whose influence proved definitive.
