The former Arsenal captain has experience in both leagues and feels that the Primera Division is tougher despite the fact that his club and Real Madrid are the only teams capable of winning the title.
"Liga boring? No, I was surprised discovering that the Spanish League is more competitive than Premier.
"Barca and Madrid are so strong and it is difficult for other clubs to keep their pace. But in England you can win the Premier League even if you lose five or six games.
"Here, if we lose or draw one match there is the risk that the Liga is already lost, so it is more difficult. Besides Spanish teams are tactically stronger, it is more difficult to score and make assists here."
