The prospective signing of Gareth Bale could see Dele Alli rediscover his sensational old form at Tottenham, according to Alex McLeish.

The former Scotland manager, speaking exclusively to Football Insider assistant editor Russell Edge, admits the 24-year-old once looked like a “player from another planet” and that a new marquee signing could kickstart his career once again.

As revealed by Football Insider on Wednesday, Tottenham are in talks to re-sign Wales international Bale from Real Madrid on a prospective loan deal which could be made permanent in the future.

Bale left Tottenham back in 2013 for what was then a world-record transfer fee.

McLeish suggests that the threat of losing his place in the side to a world superstar like Bale could be the catalyst for Dele to up his game to his former levels.

McLeish told Football Insider: “He was looking like a player from another planet – the goals that he scored, the ghosting into the box.

“The fact that there’s the addition of Bale, maybe that’ll all come back, maybe it’ll all come back and the motivation of: ‘If I don’t improve myself, Jose Mourinho’s going to kick me out the team.

“That’s the challenge for Dele Alli and it’s now time for Dele Alli to come back to that form of two, three years ago. I’ve seen it in a lot of young players.”

Dele scored nine goals and contributed six assists in 38 games for Tottenham last season.

He started Sunday’s 1-0 defeat to Everton but was substituted at half time by Jose Mourinho.
