I assume it's a reference to the later stages of Nistelrooys career, where he'd score goals but the team as a whole wasn't performing good enough and we looked miles better with a more mobile striker like Saha
Yeah I agree with this.
Zlatan's still a quality striker but, just like RVN in his later years, his lack of pace and mobility slows the team down and restricts the scoring opportunities for other players.
There are clear parallels. Like Zlatan, RVN was a brilliant goalscorer but we fell away as a team during his latter years. Although there were other reasons for that (failure to replace Stam properly, decline of Keane) his static play was surely a factor. It's the same with Zlatan now.
People can say Zlatan is scoring lots of goals, but how many would Martial have scored had he started up front every game? Maybe not as many as Zlatan has got, but surely he'd have been in double figures right now.
Then you've got to factor in the added benefit we'd have as a team. We'd be able to play the fluid attacking game we played with Ronaldo-Rooney-Tevez, pulling defenders all over the place, and oppo defenders would have to drop deeper, creating more space for the likes of Pogba and making it more difficult for teams to press us.
As a centre-half at the level of Maguire/Shawcross/Michael Keane, surely your most desired opponent is a big target man who you can battle with all day. Nippy players constantly moving around are much harder to handle.
None of this is to say Zlatan was a bad signing - he'd be a brilliant option against certain teams. I would just rather Martial was starting ahead of him.
