Gareth Bale has been tipped to make a major impact at Tottenham by the man who has won more Premiership titles than any other, Ryan Giggs.
Giggs has been impressed with what he has seen of Bale
The Wales captain made his debut in the division at 17, the same age as his compatriot Bale who has sealed a big money move to Spurs from Southampton.
"He has talent, temperament and should not have any problems," said Giggs.
"My advice for Gareth is to just carry on with what he is doing, that is why clubs have been interested in him."
Bale, who was born - like Giggs - in Cardiff, could have joined his national captain at Manchester United, but preferred the prospect of regular first-team action at White Hart Lane.
"It has been totally his own decision where he goes, he has plenty of advice I am sure," said Giggs.
"But a talent like that deserves to be in the Premiership, and that can only be good for Wales and Welsh football generally.
"We need as many players as possible playing in the top league and he has the physical attributes to be a top player.
"What he has to do is keep progressing like he is. He has a talent, and what I have seen of him, I have been impressed.
Right from the outset when we first saw him, we all knew that Gareth was very special
Wales manager John Toshack
"He has a good attitude, good behaviour and the way he conducts himself suggests he is also mature."
Bale's initial transfer fee is £5m, but this could rise to £10m, a sum that would smash the record £7.5m paid for a Welshman when John Hartson switched from West Ham to Wimbledon.
The left-back, who became the youngest Welsh international when he played against Trinidad & Tobago in May last year aged 16 years and 315 days, will miss Saturday's friendly with New Zealand because of an ankle injury.
But national manager John Toshack is desperate to have the prodigy available for next week's Euro 2008 qualifier with the Czech Republic in Cardiff.
"I don't think Gareth will have been distracted by what has been happening over the last few days, but it will be a risk to play him against the Czechs because of his ankle," said the Wales boss.
"If he is not 100% fit for a such a big game I will not pick him. It will be very disappointing but it will be too much of a risk.
"I feel Gareth will become a very good Premiership player. The step up is very important and we are all delighted for him.
"We have seen a lot of young lads who progress and then stop and not make the impact expected, but Gareth - right from the outset when we first saw him - we all knew that he was very special.
"We all just hope that he keeps progressing and realises the potential he has got.
"When I was his age I turned down a move to London at Fulham, I didn't think I was ready. Fortunately I waited a bit and got the dream move to Liverpool.
"Gareth has taken his time, he could have moved in the January window. But he has waited and now got the move he wants.
"He has had an outstanding season for Southampton, but at international level he has shown a maturity for one so young. We just hope everything goes okay for him."
