Tottenham Hotspur boss Harry Redknapp always believed Heurelho Gomes would silence his critics and showcase his true ability.
The Brazilian goalkeeper initially struggled to settle in English football following a move from PSV Eindhoven in 2008.
A string of high-profile blunders damaged his confidence and saw him make headlines for all the wrong reasons.
He is, however, a keeper of some distinction, having graced the latter stages of the UEFA Champions League and the Brazil national side.
It is was therefore widely assumed that he would come good once he found his feet at White Hart Lane, and a string of impressive performances this season suggest he now feels at home in the Premier League.
"He's up there with the very best," said Redknapp.
"When he came here Tony Adams, who had worked in Holland, said they'd signed the best goalkeeper in the world.
"I watch Dutch football on TV and it's a completely different game and it took him time to adjust.
"He's had a couple of dicky moments but ever since then he has got better and better and some of the saves on Wednesday (against Arsenal), particularly a couple from Robin van Persie and from Sol Campbell were vital saves."
He added: "I always knew he had the ability. I spoke to Guus Hiddink and he said he nearly took them (PSV) to a Champions League final in 2005, he's that good."
Redknapp is hoping Gomes can help Spurs into the Premier League's top four this season, but accepts that his side have little room for manoeuvre in the race for Champions League qualification.
"Chelsea are favourites (for the title) and they are a great side, with bags of ability, strength and pace," he said.
"Man United have to win at Man City (on Saturday) to stay in it and we have to win (against Chelsea) to push for that fourth spot. I am sure that after these games it will be a lot clearer.
"We probably are going to need to win two and draw two, to take eight points. That's the minimum, you may need more."
