Alex McLeish has been blown away by the impact made by Tottenham new boy Sergio Reguilon.

Speaking exclusively to Football Insider, the ex-Scotland, Rangers and Aston Villa manager picked out the left-back as a top talent.

Reguilon, 23, joined from Real Madrid last month in a deal costing an initial £28million and rising to a potential £33m.

He has left Spurs’ coaches open mouthed at his brilliance behind the scenes and provided stiff competition for Ben Davies at left-back.

Asked about the difference between Davies and Reguilon, McLeish told Football Insider: “There’s probably a few years between them in terms of legs, I think, and speed.

“Reguilon has hit the ground running, he’s come straight to Spurs, right in the team and he’s playing to the level you would expect a player from Madrid coming in (would).

“When you see the attacking prowess that he has, his recovery speed etcetera, that is everything that you want from a new player coming into your team.

“It’s so pleasing for the manager when that happens, when you’ve bought a new player and he’s fitted in straight away and you go: ‘Awh, we’ve got a good one there.'”

Reguilon made his seventh appearance for Spurs in Sunday’s 2-1 win over Brighton in a clear sign he has usurped Davies as first choice at left-back.

The Spain international demonstrated his huge threat going forward by providing his third assist for his new club as he set up the winner for Bale with a pinpoint cross.
