Arsenal boss Arsene Wenger admits terrorism has been on his mind after last week's attack in Lahore.

Asked if he was concerned in the wake of Lahore attacks, Wenger said: "No, but you wonder why not? Sport has become world famous and is a good thing to attract attention. I wonder about it, because in England it's more and more difficult to get any police escort. The police just refuse, especially in London.

"I have thought about it (the possibility of an attack) many times when you go the World Cup and European Championships. It happened to us at Arsenal, where we have had alerts before the game when we played at home. We kept it quiet as much as we could and it turned out to be nothing. You find a bag in the stadium that someone forgot."
