When we sign all three main targets we would have Silva, De Bruyne and Sterling as the attacking trio behind the striker, perhaps. I'd personally want Silva to stay on the left, KDB in the middle and Sterling on the right. Even though part of me wants to keep Silva in the middle, I'd rather have KDB play there so as to get him really really involved at the center of attack and get him to replicate his last seasons form. Hopefully, he will bag a record number of assists whilst scoring an impressive number of goals too.
I agree, I think Silva would be more effective on the left than KDB initially, perhaps give them both a free role to interchange with one another
