Everton have signed goalkeeper Maarten Stekelenburg on a three-year deal from Fulham for an undisclosed fee.
The 33-year-old, who played under Koeman at Ajax and on-loan at Southampton last season, becomes the new Everton boss' first signing at Goodison Park.
"I'm very happy - things have moved very fast over the last couple days," Stekelenburg told evertontv.
"He [Koeman] has come to Everton and he called me a few days after asking if I was willing to follow him. It wasn't difficult to make that choice.
"He's one of the best coaches - he's straight talking, he's fair and he has confidence in me which counts as well.
"I've been here [in England] for a couple of seasons and I love the Premier League. It's fantastic that I can stay."
Manager Koeman added: "Obviously I know Maarten well having worked with him at two clubs before.
"I know through his professionalism, hardworking approach and personality he will fit in well with what I will be building at Everton."
Stekelenburg, who was a World Cup runner-up with the Netherlands in 2010, spent almost a decade at Ajax, winning two Eredivisie titles and three KNVB Cups.
He joined Roma in 2011 before moving to Fulham two years later.
Stekelenburg spent the 2014/15 campaign on loan at Monaco before making a temporary switch to Southampton last season, where he played 25 games after a long-term injury suffered by regular stopper Fraser Forster.
