Talking to The Times, the former Newcastle boss said: “He was clever and analysed. When you explain things to some players, you have to repeat them. Xabi was one who learned quickly.
“He’s a big name, good professional, good lad, clever, doing really well so I understand why [Alonso is being linked with Liverpool]. [But] imagine Steven Gerrard was around and doing well. Then it would be: ‘Gerrard!’ With social media everything is going too fast so that people don’t see the big picture.
“He was in the academy, then the second team at Real Sociedad. That gives you some experience and then he went to Germany. It’s not easy to go to a new country and be successful, so he has done well. He has the potential to be a very good manager and if he has good players he will be successful, but then can he do it for five years, ten years? I don’t know.
“He can go to any top side now but they will be expecting to win the title. And if you finish second, maybe it’s a great season but people will say, ‘Oh, he’s failed.’ ”
