Hojlund was statistically the best finisher (highest conversion of chances) in EPL, last season . Zirkzee looks like a menacing threat, as well. So there is no reason, so far, for us to think that CFs are our problem.
Our problems seem to be:
1. Sorting midfield and defense. Midfield lacks players we need, defense needs coaching, time and benching Magalof + Evans
2. Fixing style of play into something that concedes less and creates more (offsides don's count). Mount needs to be Bruno's sub+rotation used well rather than playing with him
3. Letting goal-scorers like Garna, Zirkzee and Hojlund play enough minutes and creating chances for them + continuing to start Amad. A depth better than Rashford and Antony would also be nice but we are clearly stuck with them. We cannot really add more wingers until we get rid of those two and Sancho
