Alex McLeish has tipped Leeds United to launch transfer raids in Spain and south America to bolster the squad this summer.

The former Scotland manager, speaking exclusively to Football Insider, insisted Marcelo Bielsa would leave “no stone unturned” in his hunt.

The Athletic’s Phil Hay revealed he has been told Leeds want to make as many as five new signings during the summer transfer window.

Leeds brought in four new faces into the first-team squad last summer in Rodrigo, Diego Llorente, Robin Koch and Raphinha.

Meanwhile, Jack Harrison returned on loan and Helder Costa and Illan Meslier converted their temporary stays into permanent ones.

The Whites also strengthened their under-23 squad with the likes of Joe Gelhardt, Sam Greenwood and Cody Drameh.

However, as revealed by Football Insider, Leeds are set to lose Ezgjan Alioski to Galatasaray on a free, while Costa could be sold to raise funds at Elland Road.

With numerous signings expected, McLeish suggested Bielsa could return to his former stomping grounds for targets.

Asked if he thought five signings was enough, McLeish told Football Insider’s Russell Edge: “Yeah, I would think so. Bielsa will probably be looking at the South American market and the Spanish market, I would think, in terms of their language and knowledge.

“I’m sure he’ll have a good bunch of recruitment guys at the club. They’ll be doing the algorithms and all the modern-day research stuff.

“It is a bit more advanced than having your old scout and saying: ‘Go have a look at that guy. See what you see with your eyes.’

“Bielsa will have the full works there in terms of no stone left uncovered.”

Bielsa managed in Argentina and Mexico early in his career, while he also took charge of the Argentinian national side.

He also spent time with Espanyol and Athletic Bilbao in Spain.
