After completing the transfer of Gyökeres deal the balances are likely to be upset. 
But it all depends on his performance at Arsenal.
I'll pray for him not to end up like Nunez. He also had a spectacular scoring effort in the Liga Portugal before coming to the PL as you remember.
If this doesn't happen Arsenal can finally be in the title race for real - I mean till the end! Not only here but also in the CL.
I really pray that does not become Arsenal’s fate with Gyokeres after his signing this summer. If Gyokeres can guarantee a total of 30 plus goals next season it would go a long way to boosting Arsenal’s title chances next season. The club has also realised how important it is to keep a good squad depth and have made efforts to improve in that aspect this summer so hopefully Arsenal will be able to win a trophy or two this season.
