Eredivisie is a really difficult league to predict talent.

Sometimes a 25 goal forward turns out to be a Luis Suarez or RvN.

Sometimes a 25 goal forward turns out to be and Afonso Alves or a Mateja Kežman.

He relies on pace and strength. Every PL fullback can skin him for pace and outmuscle him. He's swole but his centre of gravity's pretty poor compared to someone like Martial who you just cannot knock off the ball. All 3 of Lingard, TonyM and Rashford are much faster over short and long distances. Memphis looks gassed for 5 minutes after every counter attack break.

He relies on a bag of tricks. He doesn't have the time or space to use any of them in the PL. Rashford's the only other player who has that flair but he uses it very sparingly when it's effective. Memphis does it for highlight reel but achieves nothing.

He relies on dribbling, his close control is nowhere near precise enough to actually beat a man in the PL. There's a mountain of difference between the technical ability of Martial, Lingard and Rashford compared to Memphis. Caveat being that this is just in the PL. He does insane things against teams like Brugge but looks like a donkey in England.

His long shots/freekicks. Watch the actual distance goals he scored in Holland. Maybe 1 or 2 top corner screamers. Most of them are just 30 yard shots that trickle and bumble their way in because of atrocious keeping. Rarely troubles the keeper with his tame shots from outside the box.

Decision making and intelligence. Lingard's easily the best in the class at this - movement, quantity/quality of runs, positioning, quick 1-2s in tight spaces etc. are flawless. Rashford's not far behind him even though he's less effective in the centre but very clever out wide. Martial is a bit like Memphis. Not huge amounts of intelligence re stretching the pitch wide, cutting in when advantageous etc. but the difference is Martial likes the ball at his feet because he can actually do the damage to the opposition. Memphis can't. He either needs to grow a football brain or improve his technical ability drastically.

BUT

Put him in up against an average European team and he starts playing like Ronaldo reincarnated.

Just needs the pace, strength etc. turned down a couple of notches to show it. Which makes a lot of us frustrated because the moment the difficulty is ratcheted up just a tiny notch he's just incapable of coping.

The talent is clearly there but then you compare him out wide to someone like Tadic or Chadli and you're brought back to reality and just have to accept he can't cut it at the highest level.

I think a spell in Ligue 1 or Serie A would do him wonders. I can't see him coping in England, Germany or Spain.
