He did really well vs Leipzig IMO playing centrally. His movement is one of the big plusses you get being central! He has the poacher instincts to find space that Martial and Rashford don't. But yeah he has to develop with his back to goal, only way to do it is with game time though. Part of the problem with his other games was he played in a full rotation team there, so our whole level dropped, not because of him necessarily. The benefit would be having Rashford and Martial stretching the pitch and being inside forwards anyway, so I don't think itd hurt us. Cavani needs to be used for the more important games anyway, but Greenwood is definitely good enough to rotate in for smaller ones as a striker.
Greenwood's starts as a striker this season:
Leipzig home - scored nice finish from an angle, apparently he had another shot that was saved but I don't recall it
Leipzig away - won dubious penalty, should have sent Rashford through on goal soon after they scored but instead chose to go alone then a tame shot that was easily saved, 4 other shots, one saved, one blocked, 2 off-target
Arsenal home - similar position to his goal against Leipzig but weirdly chose to shoot near post that was saved without difficulty, otherwise anonymous
Southampton - had two huge chances to score but wasted both, incredibly shooting well wide having gone round their keeper, the other intercepted a pass from their keeper who was then out of position but poor touch followed by a tame shot that was easily saved
Watford - anonymous
In most of those games we were playing 4-4-2 diamond or 5-2-1-2 in Leipzig in the first half (not sure what the formation was in the 2nd half when van de Beek came on for Telles)
If you were confident that his finishing would be 2019/20 standard, rather than 2020/21 to date, then it might be worth the risk but otherwise it strikes me as being crazy. An out of form Martial, playing as a central striker, still manages to link the play.
Even last season, in far better form, Mason, when playing as a central striker, was more likely to be anonymous, than to impact the game. Alkmaar (missed one huge chance) and Astana away games. He did ok against Spurs but hardly frightened them, just one right foot shot from an angle that forced a decent save. Everton away game, Greenwood limited to one header that went wide and one key pass for a shot from outside the area. He scored in the Astana home game.
