Isak will be a brilliant addition to any squad. Having Isak on the pitch should give them the edge over their nearest competitors and they should win the Premier League. Slot will have a headache rotating his squad while Guardiola and Arteta are probably having sleepless nights 
Yeah brilliant on paper but let's wait and see what he brings to the new team - we saw Benteke, Andy Carroll deals to Liverpool and how all hype and noise ended. A move that ruined their promising career forever.
