The Yorkshire Evening Post's chief football writer Phil Hay has said on Twitter that Leeds are hoping that forward Patrick Bamford is still being assessed following a knee injury that he sustained playing for the under-23s team last week. 

This would be a major setback to a Leeds side that are flying high at the moment, and could be an injury that could curtail their momentum.

As Hay said, the club are hoping that the injury is not serious, but manager Marcelo Bielsa should be prepared for all possibilities if the injury proves to be long term.

While Bamford has primarily been used as a substitute this season for The Whites, he has certainly been part of Bielsa's plans, playing a pivotal role when coming on for the final half hour of the match usually. Now the Argentinian boss will have to look at a way around that.

It is an injury like this that could stunt the momentum that Leeds have built so far this season. The Championship is all about momentum, and keeping hold of it as long as possible, and this will be something that Bielsa must manage well.

Leeds sit at the top of the Championship table with four wins and two draws from their opening six games this season, but face a tough test at Millwall this Saturday.

These are the trying tests that prove the worth of a manager, and if Bamford's injury proves to be worse than Leeds expect, it's down to Bielsa to manage through this situation.
