Of course the Premier League is the most difficult league in the world because it's so even. I think you can't really compare other leagues with the Premier League. In the Premier League, every team can beat every team, and in football, that's something where you can have surprises.
I think La Liga is the best league in the world.

We have been out of the top-flight for 16 years and I am thrilled for the whole club and our incredible fans that we are back in the Premier League.
It's such a crazy league, the Championship. People used to say that to me, and when you are in the Premier League, you don't really take notice. It's a good league; it's tough, and I like it. But the Premier League is where I want to be, with Villa.
It is a normal thing for a young player to want to prove himself in the Premiership.
A return to the Bundesliga would be super.
I say always that the Premier League is the best league in the world, and it's an honour to play here.
That's the English Premier League. You can win against the best teams and then lose against the last.
Experience is a big thing when playing in the Premier League - it's a different game to any other league.

Arsenal are the club that plays the best football in England, so I really wanted to come here.
For me, the Premier League is the most difficult championship in the world, and I am so happy here.
I'm happy in the Premier League.
It's very exciting, everyone wants to see Aston Villa back in the Premier League and kicking on from there. It's great to see this club with such a rich history of being in the top flight, it's an exciting prospect.
To play for a team in the Premier League would be amazing and that's what I am going for.
