This is a depth signing. Abramovich has signed it seems dozens of these 8-15 million dollar players in his tenure. Moses is a strong build player who can player up top or outwide. He is a different type of player than Marin, who is expected to be on the bench. Marin is a playmaker while Moses is more of a bruiser and strong player. And unlike Lukaku, he isn't demaning first team action. I don't see how Moses "takes up a spot." Malouda, Benayoun are likely gone, and De Bruyne, Lukaku and McEachran are going out on loan. Oscar, Hazard, Marin, Mata, Moses, Torres and Sturridge are your guys for that 3-1 formation up top. Lampard, Essien, Ramires, Obi Mikel and Romeu are going to be in the 2 holding spots. Then Meireles is on the outs. Now if they bring in Cavani, Hulk or Schurrle, then different story.
