Arsenal attacker Alexis Sanchez rates the Premier League as the toughest in the world.
Alexis left Barcelona for the Gunners in the summer.
"Compared to the other leagues I've played in, I think this is the hardest and I like it a lot, I really do," Alexis said.
"Before I signed, people had told me about how Arsenal were a big club with lots of quality players. Now I'm here I look at all the players during training and realise just what fantastic quality they all have."
