"La Liga have bought marquee players – I think Ronaldo obviously, Kaká and Ibrahimovic are three of the best players in the world and any team would like to have them," Ferdinand said. "They've all gone to La Liga alongside the likes of [Lionel] Messi, [Andrés] Iniesta, Xavi [Hernández] and people like that. So they've got a claim to being the best league in the world.
"I think the last three or four years we've had English teams in the semi-finals of the Champions League so that says it all about where the Premier League is at at the moment. This season we have to wait and see if we're still the best league in the world or not."
