Middlesbrough striker Mido admits teammate Afonso Alves is suffering from a culture shock after several seasons in the Dutch league.
"I don't want to underestimate the Dutch league, it's a very good league for young lads who are talents and coming up and I've played there myself," the Egypt star told the Evening Gazette.
"I was lucky enough to play for a massive club like Ajax and win trophies but the pace is a lot faster here and the defenders are tougher.
"Afonso was a little bit surprised in the Sheffield United game when he saw how physical the defenders are.
"After the game we were speaking and I said to him that in this country you face that in every game.
"For me it isn't a problem because I know about it. Players like John Terry, Rio Ferdinand and Kolo Toure at Arsenal are all tough, but if I fight any of these defenders in the street I will take them! But for Afonso it's been a little bit different so far because he didn't know. He thought Morgan wanted to hurt him and this is the difference mentally. Afonso needs time to get up to the pace of English football but you can see in training he is a very good signing for us."
