Actually I think the way we interpreted the 4-3-3 is more defensive mi ded than a 4-4-2 would be. With the 4-3-3, when we weren't in ball posession, Bona and Cerci dropped deep and we defended in a 4-5-1. If you start with a 4-4-2 as basis then you put 1 CF more and you take away obe midfielder/winger, which is more offensive minded and as we have only two strikers in match form (Niang according to Sinisa has 15-20 Minutes in his legs), not the moment to change to it even if we wanted to.
I agree, it would be better indeed to see 451 without having the ball rather than 442 against them. Although, am not staggered on how we put this idea to good use. Inter did it with full conviction against Roma last night with Ljajic and Perisic dropping back like they were fullbacks. I don't see the same determination in Cerci and Bona yet. Therefore, am still edging towards 4-4-2 as we would have 2 men upfront to pass to rather than 1. The only issue, as you said, is that Niang only has 15 to 20 mins in his legs. Limited CF bench options so
