Speaking to The Times, Rooney said, "England will need to defend well on the flanks against Spain because their brilliant two young wingers provide their main threat. Lamine Yamal will be full of confidence after his brilliant goal against France and he reminds me a bit of how I was at Euro 2004 – a teenager having the time of his life.
"Fear? Young lads like him, Nico Williams and Mainoo haven’t lived long enough to know it or understand what it is. On the big stage of a European Championship, they’re just playing and enjoying it and having fun, and normally that’s the best way to play the game."
He added: "Williams, for me, is exceptional. He reminds me of Cristiano Ronaldo when Cristiano was young. He’s a big lad, he’ll take the ball and sometimes tries too much but usually makes the right decisions. He is an incredible threat in one-on-one situations and scores goals as well. England need to be really careful with him."
