I'd say the strength of having him in the second striker role is his graft. Him and Richarlison - who I think dovetailed together really well - put in so much work pressing defences and narrowing passing angles. Look at the job they both did on Jorginho. Or the goal v Brighton. Or the pass that came from Gylfi to Richarlison in both the derby and then for the penalty at Old Trafford.
But yeh, I'd also agree with trying a three, especially against teams who are going to sit back.
I'm not sure on a diamond if we have the personnel to currently make it work.
The Brighton goal is a good reference point.
Takes the ball deep off the far side of a corner with loads of space to counter.
He's got the drive to take it most of the way. He make Bernard (a winger!) look like an u15yr old.
Sets ups Rico for the goal - but that's in space on the counter, not from usual build up.
The first attack of that game also illustrates perfectly what Silva is trying to do.
Quick attack from midfield wing, Sig then gets space to move quickly into box to receive cut back from Coleman.
He fluffs his lines, maybe put off by Walcott who should of being drawing players away.
But its a poor coach who is basing his strategy on these moments. There has to be more of a foundation.
I reckon the solution is to get Gylfi more often in the build up in tight - once the play leaves that area he is then able to make runs and find space to receive it back, ideally. You keep trying that all the way up the park.
The tactics change once the space is squeezed. He can still pick the moments to get into the box, but positioning him there is not playing to his strengths or the teams strengths.
As argued before, the graft you talk about with Rico, would be better done by Bernard.
Both Bernard and Gomes play better if
positioned in attacking tight spaces, in contrast to Sig
moving into them
Also Sig's got the engine to cover and get back and defend with Gana when the ball is lost.
Agree we don't have the players atm for a diamond.
It doesn't work because we have Gana.
If you have Sig and Gomes either side of DM it needs to be one with better quality on the ball.
A DM good enough to dictate play from one side to the other.
This also allows a player like Bernard to play the attacking point of the diamond.
But we also would be left with Rico and Walcott leading the line, maybe Rico and Lookman. Not sure that would be good enough.
If they are going to stick with Gylfi then Decoure would be a step in the right direction, not exactly the answer but better on the ball.
A decision has to be made, either get someone like Decoure with intent to upgrade and keep Sig and Gomes.
Or keep Gana and get two exceptional ball playing midfielders either side of him.
With Gana and one other not being an option.
