If Thomas Tuchel's goal-scoring problems weren't big enough heading into the new Premier League season, he could be about to lose one of the club's top contributors.
With Kai Havertz and Armando Broja looking like the most natural players to fill the middle spot in a fluid front three, with Raheem Sterling's attacking instincts added in, Chelsea are in need of a consistent stream of goals.
The Blues haven't replaced Romelu Lukaku who still finished top of the scoring charts in all competitions last season, but only managed 15.
