Walker was labelled with that tag by sections of the foreign media after a superb performance for England Under-21s against Spain during the summer European Championship finals.
Big time: Walker is in line to make his full international debut against Holland
He reaped the benefits of a season-long loan at Aston Villa, signed a new five-year contract at Spurs and has now been included in the England squad for Wednesday's home clash with Holland at Wembley.
But Walker knows there is much work to do before he can realise his double objective for club and country.
Catching the eye: Walker has been impressive for England at Under 21 level
Walker said: 'It's been a whirlwind two years. There have been a lot of big steps in my career
'The summer has been all football but it's all been good. The Tottenham contract, I'm happy for, and hopefully I can get into the team now and push forward there.
'There are a lot of quality players at Tottenham and it is going to be difficult.
'But it is massively important for me to be playing week in and week out. I've had a taste of it at Villa, playing week in and week out at Premier League level.
'I'd like to think I've proved I can play Premier League football and hopefully the gaffer (Harry Redknapp) puts some trust in me and plays me.
'I feel at Spurs I need to get a couple of games and show the gaffer what I can do and also the fans who have seen very little of me.'
Walker has been on the verge of an England breakthrough for a considerable time and Glen Johnson's absence through injury against the Dutch has enhanced his chances.
He said: 'It should be a special occasion in anyone's career to play for your country.
'Who wouldn't be excited? It's what I dreamed off since I started playing football, to play for England, and hopefully it comes.
'Playing for your country is massive at any level and to go to Euro 2012 would be something special.
'It would be a special moment in my career - and I want to play.
'But I've got to take small steps rather than looking for a year's progress, I want to take small steps and see what happens.
'I'm just turned 21 and I'm willing to learn, and hopefully I can learn off the likes of John Terry, Rio Ferdinand here, experienced defenders, and take a leaf out of their book.'
Loan star: Walker spent the first half of last season at QPR
The level-headed Walker plays down the comparisons with Roberto Carlos but believes he made a favourable impression during the Under-21 finals in Denmark.
Walker added: 'It is a good level, it was a good experience for me, getting away with England and hopefully preparing myself for future tournaments to come.
'It did help me. I did well although the tournament for the team was not what we expected.
'It was on TV and hopefully I did the right things.'
Walker was a striker in his younger days and admits he has never lost that ability to surge forward down the flanks.
He said: 'I'm a defender. My main objective is to defend. Going forward is just a bonus of my game and I just want to learn off defenders really.
'But I started off as a centre-forward and that has probably helped me out a lot.
'I like to go forward, I like to attack, and wingers don't want to track you back these days.'
