"It would be a very brave and bold move by Celtic and I realise there are a lot of other managers still in the frame," Nevin told BBC Scotland. "But I think it's quite far-sighted for Celtic to think of this.
"We have heard some of the names mentioned, even Scottish ones, wouldn't be willing to give up English jobs. So they have to think of somebody who is an up-and-coming manager who has great knowledge of the areas Celtic need to buy in.
"One of those areas is beneath the Premiership in England, because Celtic can't afford to bring players in from the Premiership, and also players from abroad. Roberto's knowledge of the Spanish scene is second to none - he did a lot of work for Spanish television.
"His knowledge of different markets is great - that's very, very important for a chief executive - and also he plays a really attractive and enjoyable style of football, which Celtic fans would enjoy."
