Leeds United can be quietly pleased with how their transfer window went, but if there was to be one criticism it would be the fact that they’ve failed to sign a central midfielder.

The Whites were publicly in the market for a new midfielder with Michael Cuisance almost signing for the club and Rodrigo De Paul being a widely-reported target.

However, with neither of those players coming in, Leeds have to play the hand they’ve been dealt, and that means that Mateusz Klich will remain as a starting midfield option.

The Pole has started all-but-one of Leeds’ league games under Marcelo Bielsa, but despite being one of the Argentine’s favourite players, he may now have to prove himself all over again.

The Yorkshire club clearly weren’t all that comfortable with Klich being their first-choice in the middle of the park, hence why they were ready to part with £18m for Cuisance, but now that Klich looks like he’s going to retain his spot he has to make sure he’s at his absolute best.

The January transfer window is just over two-and-a-half months away and if Klich doesn’t show he’s up to scratch, Leeds may well be back in the market for a midfielder by the time 2021 rolls around.

Luckily, this isn’t a new task for Klich. He had a lot to prove at the beginning of the 2018/19 season, coming back into the fray after being loaned out under Thomas Christiansen and Paul Heckingbottom, but after Bielsa showed a bit of faith in him he made sure to make the most of his chance.

He went above and beyond to prove that he was good enough to play for his new manager, contributing to 10 goals in the first 16 games of the season, and since then he hasn’t looked back.

The 30-year-old, who was described as a "great player" by ex-Leeds striker Jermaine Beckford in July, now faces that same task, and to be fair, he looks more than up to it, contributing to three goals in the opening four games of the season.

However, he has to continue to prove that he’s good enough at this level, or else Victor Orta could once again be looking for a player like Cuisance who could easily act as Klich’s replacement.
