even Aubameyang has not been able to make a good contribution on the Chelsea front line this season so if Chelsea officially gets Ronaldo I think Aubameyang will be Graham second choice in the second half of this season.
Romours staggering about the Ronaldo move to Chelsea, well I don't have any doubt yet, let's wait for the outcome. Graham potter needs an experience, well position balance striker that is capable of scoring goals for the team. Chelsea need sharp striker, and Pierre Aubameyang doesn't fit in the pattern of the blues. If Cristiano Ronaldo deal is been triggered and he comes to Chelsea, there's every possibility that he's definitely going to be a starter under Graham Potter.
It is true that Aubameyang has not been able to show anything special for Chelsea's game. And that's what makes Chelsea have to have players who can contribute more than the players they have now. Rumors about Cristiano Ronaldo are still quite wild at the moment and all the rumors have not even been confirmed. So let's wait until the World Cup is over for an answer.
