Frank Lampard wasn't a creator though, he basically had his role changed to a SS at Chelsea when it was discovered he was a very good finisher, different type of player. I've watched a few videos of Bruno Fernandes and I know videos don't dictate the whole story but the idea of them (Highlights vids and individual match vids) is they are designed to show you the very best of the player, and nothing I've seen has impressed me much, and his numbers in a 3rd tier league don't matter much either IMO, he just reeks of Fred to me, a mid level type of player to pad out the squad who has some nice CL stats and "Bossed City" but who in reality wont elevate this team. We have some core missing pieces in the starting 11, Bruno Fernandes doesn't fill any of them, at best he's cover for Pogba, now if we pissed money like PSG and Barca then sure, buy him as the 6th signing of the summer to increase the depth, but that's not how we work, buying him will mean we don't buy somewhere we truly need to invest the money IMO.
He's not suited to the front 3 and I really don't see him fitting into the midfield 3 with Pogba, he'd just be cover.
I'm not sure we can say what Ole prefers, I mean this isn't his squad and we've been using the diamond more and more for starters as Ole recognizes that we have no RW and that Rashford, Martial and Lukaku all do better in the split striker system than with one of them trying to lead the line as none of them has great hold up play. Bruno Fernandes hasn't done anything outside of 2 seasons in Portugal, he's an unknown quantity at the top level, much like Gomes and Pereira who have yet to have a sustained chance in the squad to see what they can offer.
I don't think it's a safe assumption thouugh, to me we've looked better when using the 4-4-2 diamond with a false 9, than when we've used 4-3-3, and Joao Felix fits right into the false 9 slot, where Bruno fits on the bench in either formation.
I'm a fan of Neves and Sancho but with Neves there are legitimate concerns over whether he can play the holding role in the system we use, and whether he's dynamic enough. Sancho is a player we should be looking at but probably the summer after IMO.
I don't think being flexible is a bad thing when your intent remains the same, we've switched formations during games recently without missing a beat. As for an alternative, like I say I'd use the 2 Academy players rather than spend any of our budget on him, but if you want a name I'd say Pellegrini from Roma, he's got a £22M buyout clause and is more versatile.
