There are so many other examples in the Premier League of players who are the best in their country and make a move because they are really ready for a level higher. If they come to the English top flight, it turns out they need a period to adjust in terms of pace, aggressiveness and physicality, especially as a midfielder.
Tottenham is not a club that always wins, but we are trying to create something. It's not easy to fight against European monsters, but it is a motivation.
Playing Bayern is never easy.
You cannot find one team in the Premier League who can win at a place like Old Trafford regularly. The word 'regularly' makes it sound easy to win.
I got kicked out of the league because I had a hard time sustaining at the quarterback position.
I believe that if I committed to basketball, I could make an impact in the NBA. I now see football as my job and my greatest challenge.
Playing Chelsea is as tough a test as you'll get in Europe these days.
It's difficult to get ready to face a player like Cristiano Ronaldo. He's a goal animal.
Not many teams will come to Arsenal and get anything, home or away.
To beat City twice is no easy feat.
Thierry Henry, he was definitely the best. He was just too quick. Oh God, what a player he was. I was so relieved when he went to Barcelona. He used to have everything. You couldn't even kick him, he was big and strong, oh, Jesus, he was a nightmare
Rivaldo was fundamental for me accepting the challenge in Bunyodkor.
When I left Ajax in 1999, I travelled to Liverpool and spoke to Houllier. I was shown around Anfield and also met with the chairman and a couple of the players. I thought about it, but when Juventus came to the table, I came to the conclusion that it would be a bigger challenge to play in Italy.
Marcel Desailly was pretty hard when I played against him in a Milan derby.
Every TV timeout, I went up and said it right to Brady: 'Please keep trying me. I'm going to take it from you.'
It's not easy to score three goals in 70 minutes.
I think Crystal Palace is always a tough place to go.
It's my objective to make sure Schalke are successful again. It's a huge challenge for me to help the club to the Bundesliga title again after years without winning any titles.
I like the challenge, week in, week out, of trying to play good, consistent footy.
I have crossed Suarez on the field and it was a pleasure. He is a great forward and that always means a challenge. I would like to swap my shirt with him.
To score three goals at City is not easy.
I do not think it is very easy to win away from home in the Champions League.
When I took over at Everton, the challenge for us was to try to go toe-to-toe with a club having success in Europe and sometimes competing for the Premier League.
It was very hard to go through life as a small boy supporting Atletico.
When I used to come to Anfield as an away player, I always knew it was going to be a hard game, no matter what kind of form your team was in.
