The goalkeeper coach joined from PSV Eindhoven this summer.

Koeman took charge at Everton last month following Roberto Martinez’s sacking before the end of last season.
He brought several members of his coach team with him to the club, with brother Erwin Koeman and Jan Kluitenberg both joining him at Goodison Park.

He also made a move to bring a new coach into his setup, securing Patrick Lodewijks from PSV Eindhoven.
And the Dutchman believes that the club have one of the best in the business in their new goalkeeper coach.
"The most important thing is really that he brings a lot of qualities in the goalkeeper coaching to the goalkeepers,” he told evertonfc.com.
“We try always to get the best out of everybody and that is one of the reasons I am very proud that Patrick is joining us at Everton. I think he's really one of the best goalkeeper coaches that we can have here."

While Koeman will be hoping that Lodewijks can have a big effect on the goalkeepers at the club, he must first decide who will be their number one next season.
Tim Howard left at the end of last season and currently they have Joel Robles and Maarten Stekelenburg as their options in the position.
Neither is particularly viewed as a long-term solution though, and it remains to be seen if Koeman looks to bring in a new number one for Lodewijks to work with.
