Leeds United have seen a wide variety of players come and go at Elland Road in recent years, with naturally varying degrees of success.

Whilst some have had forgettable stays, there were plenty who came and impressed before leaving for bigger and better things.

In the case of Stuart Dallas, though, they were repaid with a level of longevity and leadership which is paramount to any club’s success.

The 31-year-old epitomises everything good about the Whites since their revival under Marcelo Bielsa, with his unrelenting energy making him the perfect player for the Argentine's brand of high-intensity football.

Having been signed by Uwe Rosler for just £1.3m back in 2015, the Northern Irishman has gone on to play 267 times for the Yorkshire side in both the Championship and the Premier League.

Despite having featured all across the defence and in midfield, a return of 28 goals and 18 assists is certainly solid.

It marks a huge blunder from Brentford to have allowed such a stalwart to leave for so cheap, especially given how he has blossomed since departing west London.

The defender became a mainstay under Bielsa, featuring 45 times in the Championship as they strolled to the title in 2019/20 and playing in every Premier League game in the following season.

It therefore makes his recent injury troubles even more frustrating, as he was relied upon so heavily. The fact that it was an innocuous blow is also upsetting, given how he never seemed to suffer from muscular injuries.

Despite barely featuring for his current boss Jesse Marsch, the American still described Dallas as a “fantastic person and player”, as well as an “ironman”.

His importance and contribution to the success of this Leeds side has understandably resulted in an upshoot in his value, which CIES Football Observatory now cite at €8m (£7m). This marks a sensational 438% increase over his time at the club.

Rosler did not do much during his short stay at Elland Road, taking charge of only a dozen matches, but his decision to bring in the 56-cap Northern Ireland ace was a stroke of genius.

Leeds struck gold with this signing, who will hopefully feature heavily once again whenever he returns from his lengthy layoff.
