The midfielder is on a season-long loan from Manchester City.
"Iâve been a big admirer of Gareth over the years,â Martinez told evertontv. âHe senses danger like nobody, gives you composure and is full of good decisions. He establishes good relationships with players all over the park.
âHe is very unique because his type of midfielder doesnât normally exist in English football. You get a lot of foreign players coming in and playing that role really well but Gareth Barry is something else.
âHe is going to be an incredible influence on James McCarthy and Ross Barkley. He is going to provide perfect guidance for the future.â
