Swansea City manager Brendan Rodgers says the best is yet to come from goalkeeper Michel Vorm.
Dutchman Vorm has kept seven clean sheets in his first 15 Premier League games for Swansea since a £1.5m summer move from Utrecht.
Rodgers believes the 28-year-old will soon fulfil his ambition of becoming the Nertherlands' first-choice stopper.
"In this short period with us he's proven he's a top keeper at this level and he'll only get better," he said.
"He's been in the country only six months now so he's only going to improve and get better once he finds that co-ordination with the team by playing with them and getting more experience of the Barclays Premier League.
"His career is only on the up in terms of his performances."
On Saturday, Vorm will face one of his main competitors for the Netherlands goalkeeper's jersey when Swansea travel to Newcastle.
Tim Krul has also caught the eye this season with his displays for the Magpies, keeping four clean sheets in 15 league games as Alan Pardew's side have climbed to seventh place.
The 23-year-old won his first senior cap in June in a goalless draw with Brazil and is being mentored by former Manchester United and Netherlands number one Edwin van der Sar.
Rodgers rates Krul and Vorm as two of the best keepers in the Premier League, but has backed his man to dispose Maarten Stekelenburg as the first-choice Dutch stopper for the Euro 2012 finals in Poland and Ukraine.
"In terms of my eyes, [Vorm] is very much a top, top keeper," added Rodgers, who revealed he had kept a close eye on Krul's development since signing for Newcastle from Den Haag in 2006.
"I can only judge on what I see on a daily basis and on a weekly basis in his performance level.
"There's certainly no doubt I would like to see a better one than Michel because if there is someone better than him in the Dutch national team then they've obviously got an outstanding keeper."
Krul has already attracted interest from the Premier League's title contenders, with Manchester United and Tottenham Hotspur reportedly casting admiring glances his way.
Vorm's form has also put him firmly in the shop window, but Rodgers says he does not fear losing any of his best players in the January transfer window.
"I have to be honest, I have no concerns whatsoever," said the Northern Irishman, who says he has not had any enquiries for any members of his squad.
"I am relaxed, all the players here understand that this is a real good fit for them. We are a team really riding high on confidence, we are a group that has grown."
