No one knows how Villa will approach the match. If it were me, I’d probably lean toward playing this one in two phases, perhaps by starting 4-5-1, trying to blunt Chelsea, then look to get more attacking in the second. But that’s me.
The question is whether Smith will want to go all in for grabbing the first, or keep his powder dry, go for 0-0 as long as possible, and then throw on more firepower? Not at all sure he’ll want to start out with a combination that’s barely played together against such a strong side, however much he might want to see them all together.
