"Game after game he's winning confidence" - Vitor Pereira's verdict on Wolves summer signing

The 28-year-old has started the last three Premier League matches, with marginally better performances, but he is yet to register a goal or assist in eight top flight games this season.

Arias was also not called up by Colombia in the last international break, with the national team choosing to give him more time to adapt to English football.

Pereira has welcomed that decision and believes the attacker is getting better with every game.

"It was important because Jhon played for a long time at Fluminense," Pereira said when asked about Colombia's decision.

"They have a game model of playing in the short spaces with the ball. It's a very difficult league, but different.

"It's not easy to come here. For Jhon, he's learning the language and he's come from Rio de Janeiro to Wolverhampton, it's a big difference.

"It's a new league, very different, the physicality and pace, but he's increasing his level.

"Game after game he's winning confidence and that's important for us.

"I believe the system is more for him, he recognises it.

"Now it's easier for him to associate with the others."

Meanwhile, the head coach has admitted Jorgen Strand Larsen is still struggling with his Achilles injury.

The striker has yet to score a Premier League goal this season and has struggled for form, following his recovery from the knock and the intense transfer interest from Newcastle United.

Larsen is still feeling the effects of his injury and Pereira has admitted the Norwegian striker is unable to train properly in the week before games.

"The problem for Jorgen is that he's not working every day," Pereira said.

"In the last weeks he's worked one or two times in the week and it's difficult to be at his best level.

"He cannot have two or three trainings in a row because he needs to control the pain on the tendon.

"But this is a moment to forget the pain and he's trying to help but he's not the Jorgen that I saw in the last season, pressing everybody.

"Now he's struggling. Struggling in the pressing, struggling to do what he wants to do, to attack the space.

"But he's trying. I need to defend him because he's working, not at his 100 per cent."
