Speaking to PA News Agency, Butt said: "I think he can do better than some of the teams that will be in for him in the Premier League.
"The Spanish league is written all over for Angel. He could play in the Premier League easily. He could play for City tomorrow.
"When Angel left United (in 2020), I said to him ‘you’re going to go on and have an unbelievable career and I wouldn’t be surprised if you end up playing against Manchester United for Barcelona or Real Madrid in the next five, six, seven years’, because he was that good. And I’m not just saying that now that he’s made his England debut, I genuinely thought that a long time ago.
"He could play in the Premier League easily. He could play for City tomorrow. But then you put him in at Man United at the minute and he’s got to have the legs to go through the centre of midfield where there’s a massive gap, people run through the Man United midfield like you wouldn’t believe. Then it’s a really difficult game for him."
