Personally, if we had Griezmann at our disposal, I think the way to get the best out of him would be to emulate Jupp Heynckes 4-2-3-1 Bayern side. He would suit the shadow striker role quite nicely, and could potentially have the sort of influence that Muller did. We'd need a player with pace and creativity on either side though, like Ribery and Robben to give him that space in central areas. Mourinho's Chelsea of the 2014/15 season consisted of a Matic and Fabregas with just Oscar ahead as a workhorse no.10 which worked quite well initially. However, Oscar's inconsistency meant Fabregas would often go into the no.10 role meaning Matic would be isolated in the process. I believe Jose wanted to rectify this in the subsequent season, which is exemplified by his interest in Muller ("Is anyone in England interested in Thomas Muller? For sure. Can we, England, bring Thomas Muller from Bayern? I don't think so) but given that Muller is a Bayern Munich player, it was invariably going to be difficult to attract him, which led to him saying "The way is to bring players like [Sergio] Aguero when Man City bought him or [Eden] Hazard when Chelsea bought him. Try to be lucky and have an Alexis [Sanchez] that is not playing regularly in Barcelona. [Cesc] Fabregas is similar to Alexis, not playing regularly. Arrive at a moment where these top players really want to leave and they force it a little bit" which is the category Griezmann would fall in. Granted, "if" is the conditional clause, but provided he successfully managed to secure that acquisition, I believe Mourinho would still be the Chelsea manager. Furthermore, I'd look to replicate the duo which were behind Muller in Javi Martinez and Schweinsteiger. One player in which I can see similarities with Javi Martinez is Sevilla's Krychowiak who has had a galvanizing influence on Sevilla in the Europa League, and similarly Javi Martinez helped Athletic Bilbao get to the Europa League final (they finished runners up) in that season. Both tall and aggressive. Anybody with similar qualities to Verratti would be the ideal partner for Krychowiak. If the aforementioned was all achieved, I could envisage Griezmann helping us get back to Europe's elite. Don't think we will get him though.
