What a difference just three days make. Only at the weekend, Leeds fans were concerned with Marcelo Bielsa and the way their team was playing.

Yet, flash forward to Tuesday evening and they were defeating previously unbeaten West Brom.

It was an ideal way to bounce back from a loss against Charlton, hitting back to return to the top of the table.

The goal came courtesy of a driven effort from Gjanni Alioski as for once, Leeds were the team that perhaps didn’t deserve to win.

They had the least possession but still came out on top against an Albion team inspired under Slaven Bilic.

This was a different performance from the Whites. The frailties and lack of focus that was there against both Derby and Charlton were eradicated as a steely nature and attitude was shown at Elland Road.

There were plenty of positives to take from the win but it wasn’t all sunshine and rainbows in west Yorkshire.

Jamie Shackleton had to go off injured but the biggest concern should lie with Liam Cooper.

The image above shows the Scot trudging off the pitch on Tuesday evening as he paints a picture of discomfort and negativity.

Cooper appeared to pull up with a muscle problem and was consequently replaced by Gaetano Berardi in the first half.

Leeds did go onto keep a clean sheet but it will be a big negative that one of their most influential team members and club captain faces up to six weeks out.

The Whites are already missing Adam Forshaw and Pablo Hernandez to injury so to lose two more of their squad is far from ideal.

After all, Leeds had used just 17 squad members this season before Tyler Roberts and Luke Ayling appeared on Tuesday – a league-low for the Championship. Bielsa will have to dig deep into his reserves to ensure results are still attainable.
