There are good players, there are great players, and there are those few at the pinnacle - the Peles, Cruyffs and Maradonas.
Dave Mackay was one of the best I've ever seen. Jimmy Greaves was the greatest goal scorer, and George Best was just the best. The greatest.
Who were the best players I had ever played against? Raul, Messi, Zidane.
To play along alongside Cristiano Ronaldo, Kaka, or Franck Ribery is an honour for any footballer.
I have always wanted to play against those types of players such as Ronaldo and Neymar.
Cristiano Ronaldo, Messi and Neymar are phenomenal.
Maradona and Messi played in different times and in different positions. Messi is much more a striker, Diego was all over the entire pitch. They are two extraordinary players.
To be playing against people like Xavi and Iniesta is brilliant.
Critics have always questioned whether players like Pele from the 50s could play today. Lionel Messi could play in the 1950s and the present day, as could Di Stefano, Pele, Maradona, Cruyff because they are all great players. Lionel Messi without question fits into that category.
I played with the likes of Kelly Smith, Rachel Yankey, and Fara Williams - all these great players. Everybody knew who they were, and I was turning into one of these girls who were always my heroes.
When I first joined the team, I was playing with the likes of Mia Hamm, Shannon MacMillan, Tiffeny Milbrett - all those big-time players. It was very intimidating. I had some of these players' posters on my wall growing up, and now I was able to play with them.
I was lucky enough to play against Maradona. He and Ronaldo, when he was at Inter Milan - they were my toughest opponents.
Messi and Ronaldo are certainly the best in the world. They are both unbelievable. I am very happy to be a contemporary of these geniuses.
Messi and Cristiano Ronaldo are two players that, the way I see it, can have a spot amongst the best of all time.
Ronaldo and Messi, in particular, are above everybody else.
Messi and Ronaldo are the toughest. But I would also place Eden Hazard of Chelsea, Neymar of Barcelona, and Karim Benzema of Real Madrid on the list.
If you have Messi or Ronaldo you start the game 1-0 up.
Messi and Cristiano Ronaldo, they play on a different galaxy.
Roy Keane and Paul Scholes were unbelievable players. You cannot compare yourself to them. It is impossible. Scholes especially, I like him a lot, and I have a lot of respect for what he did for United.
I've never had an idol, but I watched Ronaldinho and then players like Xavi, Andres Iniesta, Lionel Messi. They are so good, it's impossible not to notice them.
I had the chance to play with Alan Shearer to join the list of class players I'd played with at a young age at Leeds - the Vidukas, Smiths, Kewells, and Woodgates.
Paolo Maldini never won, but he was the best defender in the world. Gianluigi Buffon never won; he was the best goalkeeper in the world for many years. But this is the story of the Ballon d'Or.
Without Messi or Cristiano Ronaldo, we would discuss Robben more often and with more appreciation.
I thought the first Welsh team I played in was the golden generation, with Neville Southall, Mark Hughes, Ian Rush, Dean Saunders, Gary Speed, and Ryan Giggs.
I was lucky to see Di Stefano, on the pitch, in person. He was a winner, as is Raul.
