Pierre-Emerick Aubameyang has reunited with Thomas Tuchel, as Chelsea snapped up the striker on transfer deadline day.
Following the robbery assault at his home in Barcelona, Aubameyang may need the help of a mask to protect his jaw.
Tuchel has said tests are going on to see whether the former Barca man can play in the Champions League game against Dinamo Zagreb.
According to Tuchel, Aubameyang is very hungry to play.
“Auba is very ambitious, he’s very focused and he’s hungry to play for us, and he is hungry to prove a point.
“That’s why he’s here. That’s what we felt from the first moment, and he is happily invited to prove a point tomorrow.
“If an issue comes up with the mask today we will not put him in of course, but there was no issue for him yesterday and I hope there will not be an issue today.
“If he is ready to start he cannot play 90 minutes so it is on us to take a decision how we manage the minutes. That he needs minutes to get his full fitness is clear so it’s on us to find the solution if he is on the bench or if he starts.”
