Speaking on The Rest Is Football Podcast, the former Barcelona and Spurs star said, "I will be interested to see what Jurgen Klopp does next. I think he will definitely take some time out because I think he's genuine when he says he has run out of energy. You can see why that job is so demanding.
"There will be a battle for him in a year's time. Or they'll be lining up for a year or so's time. I heard a little rumour that he might end up being president of Borussia Dortmund, which would be amazing."
