Marcelo Bielsa will be incredibly frustrated that Leeds United defender Diego Llorente has been ruled out of their Premier League clash against Everton on Saturday evening, according to Danny Mills.

Speaking exclusively to Football Insider correspondent Connor Whitley, the former Whites and England full-back claimed Llorente would have had an impact on the first-team by now if it was not for his injury.

Llorente moved to Elland Road from Real Sociedad for an £18million fee in October but is yet to make his Whites debut.

He picked up a groin injury while on international duty with Spain in October and suffered a further setback in training recently.

Bielsa confirmed the 27-year-old will miss the trip to Goodison Park on Saturday but is nearing a return to action.

The Argentine said: “He is now cured, but because of the relapse he is being given extra time to fully get back just to be sure.”

“It’s very frustrating for Bielsa, of course it is,” Mills told Football Insider.

“When you bring players in you want them to be fit and ready. The way that Bielsa works is very intense when you’re a new signing more so than the rest of the players.

“To bring in a player and to pick up an injury almost immediately and not recover as quickly as you hoped is incredibly frustrating.

“You’re generally bringing in players of that quality to be an immediate part of your plans and he’s not available at the moment.”

Leeds have operated with summer signing Robin Koch and club captain Liam Cooper at the heart of the defence when they have both been available.

After conceding eight goals in two games against Leicester City and Crystal Palace, the Yorkshire giants recorded their third league clean sheet of the season against Arsenal last weekend.

In other Leeds United news, Noel Whelan is in no doubt that an 18-year-old is set for a promotion to the first XI.
