Scotland's Craig Gordon has been hailed as the top goalkeeper in Britain and one of the best in Europe by former Hearts colleague Gilles Rousset.
Craig Gordon looked after Rousset's training kit
The Lyon coach was speaking after Gordon starred in Scotland's surprise 1-0 Euro 2008 victory over France.
"I don't think Paul Robinson is as good as him, even though he plays for England," Rousset told BBC Sport.
"He is one of the best, most talented goalkeepers in Europe and has the potential to be a big, big star."
Rousset was echoing weekend comments from Arsenal manager Arsene Wenger, who also revealed his admiration for Gordon.
"I think he is probably the best goalkeeper in Great Britain," said Rousset.
Clearly, the Scotland keeper is very good

"I remember him as a smashing young lad looking after my training kit.
"Technically, he was very good even then but was very, very slim and, although he built up his body since then, he still needs to work on that.
"But he has been magnificent for Hearts for three or four years now, yet he is still only 23 and still learning a lot.
"What Craig needs now is to play more international games, to play in the final stages of a World Cup or European Championships and play more games in Europe with Hearts.
"That would be a massive help in his development.
"But he has great technique and I can see him staying Scotland's goalkeeper for the next 12 years."
Wenger watched Gordon keep a clean sheet against France and told the Daily Mail: "Clearly, the Scotland keeper is very good.
"It is not the first time I have heard about him, but that is the first time I have come to watch him in person.
"How old is he? Still only 23? Then I think he definitely has the potential to play at a higher level.
"Gordon has presence and good handling and looks a very good goalkeeper to me."
Hearts assistant coach John McGlynn has since insisted that the Edinburgh club will ward off any clubs interested in the goalkeeper, who is under contract until 2009.
"It is nice that somebody like Arsene Wenger is backing up what we think," he told the Edinburgh Evening News.
"No doubt, as Craig matures, he'll want to try that level as he's an ambitious guy.
"But he signed a new contract less than a year ago and he mentioned at the time he didn't want to go somewhere and not be first choice."
