I’d say it’s down to the individual and the leagues they grew up in. South Americans tend to have dirty leagues so they are used to the hustle. Alexis hit the ground running for us.
Also another factor is the position of the players. CAM’s have it easy. They can just float around in space and pop off passes. Wingers have a fullback wanting to kick them 10 feet in their air upon arrival.
Ozil needed no time to climatise at all either.
You could just watch any Bundesliga match between two average clubs and compare it with a PL match between two average clubs and you can see the difference.
If the player is a good player with experience in a top league he should alot right in, like Allan like James.
Pepe played in a very open league, his goals most came from counters where he had the whole pitch to run into and not have someone Brexit him out of nowhere. Or teams sitting deep and he has to be clever with the ball.
Alexis had 6 seasons of experience with Barcelona and Udinese. I think it’s more about experience than the Premier League being so difficult. Pepe is a late bloomer and 18/19 was kind of his break through season. A younger player like Sane was brought with more patience in his first season, but still 5 goals and 5 assists.
Pepe has too adjust his game. Extremely dependent on his left leg. The fact that he isn’t the penalty taker at Arsenal doesn’t help him either.
As others have mentioned there are many things to take into account for a player to succeed.
League standard
Talent
Age
Suitability of players style to the team
Adaptability (how easy it is for them to adjust their game or even change it completely)
Btw, let’s not consider James and Allan as successes. They’re not the first players to have a good match and then fade out.
A recent example, Ndombele had a better debut than both and now he can barely get a game.
people seem to forget what pepe came into also, he came into a club with no stability a coach that supposedly couldn’t even communicate what he wanted to the players. He was in and out of the squad then another manager with other set backroom staff came in and with differing tactics and ideas and between all of this crap going on he still produced reasonable numbers and don’t forget he won us a game single handedly with those 2 superb free kicks etc. I think he will be great once settled and knows what is required of him and isnt being pissed about with every other week.
Probably easier to settle when playing for a world class manager with whom you already have a strong relationship than when playing for Unai Fucking Emery.
Also pretty crucial that Carlo would know both players from his previous jobs. I was a pretty big Pepe doubter last season, but let’s not pretend Emery knew how to use him (or even wanted him in the first place).
It’s pretty clear based on all evidence that Pepe needs to build up a head of steam. That might not be popular and people might expect more but we can either deal with that and let him do it or continue to suffer half performances when we do decide to play him.
He was good at the end of last season and hugely important in us winning the cup, but he’ll never be that 70 million winger we required on a performance level.
