Had an arguement with a United fan from work once who said the same of Aguero. Too lightweight for the Premier League and would soon get found out. Also remember someone saying Suarez was a one trick pony and once defenders decided to shut their legs and not mark so tight once he has turned he would struggle. Yep. Struggled like fuck he did.
They also said the same about David Silva and Hazard when they came to the PL. That they were not physical enough and defenders would stop them. Like fuck they did.
Even this season, something similar was said about Lacazette. When you've technique in abundance, all you need to do is to adjust to the pace of transition in leagues. Apart from that, it's a myth that smaller players cannot survive against those big PL defenders.
Also, this line goes to the managers as well. Guardiola is the biggest example. They said he wouldn't make in the PL with all the tough competition in this league more than others. Now his side is running away like Bayern and Barca did in their respective leagues, throws the myth that PL is the most competitive doesn't it? The biggest adjustment foreign managers have to make in the PL is not tactical. It's adjusting to the lack of winter break and the additional cup competition.
