If he wants a midfield three, right to left - Bacuna, Westwood, Delph would provide a lovely balance. If he wants a compact four, perm any four of Albrighton/Bacuna - Westwood-Delph-Tonev/Bacuna.
SLB, that's the worst tactical analysis possible, I think. They get outnumbered because they overcommit forwards, and they have no width because the three up front play too narrowly, not the midfielders. You want to see outnumbered?
I'm not sure i've ever disagreed with a post as much as the one above to be honest. And i've done some disagreeing on here!How on earth do our midfield overcommit themselves forward ?, that's about as opposite to what they do as is possible. They couldn't play much deeper if they tried!As for them not playing narrow ... ARE YOU SURE ?, you could cover all three of them with a deluxe sized duvet in most matches, as they're all usually stuck in and around the circumference of the centre circle
We're not outnumbered because of the central midfield three, we're outnumbered because the wide forwards don't support the midfield enough.
But other teams play three in the middle. Everyone plays three in the middle. If they don't, they get outnumbered. If you play a midfield four, then you have two in the middle against everyone else's three. I don't know where your getting these numbers from - everybody, and I mean absolutely absolutely everybody, knows that 4-3-3 has become the predominant formation so as to avoid getting overrun in the centre.
