I was one of those who mocked Mou's preference on having 'presence' up front. Then I thought back on what type of strikers Fergie had to lead the line. Hughes, Andy Cole, RvN, Rooney, Saha, Berba, RvP, Tevez, Chicarito. Other than Chicarito (who was lively, fast and deadly in front of goal) and Berba (who was out of favor after a year or so), those strikers did have this 'presence'. Other than being skillful, they also could bully centerbacks and made their 'presence'.
So back to our current 'options' on Martial, Rashford, and Sanchez. Judging by his records, I don't think even Fergie would have them as his strikers, as they don't have enough 'presence' to lead the line.
