Leeds United managed to pick up a win against Reading last night thanks to last minute winner from Jack Harrison.
Roberts started for Leeds against Reading, but was withdrawn in the first-half when he started feeling some pain.
The Welsh international insisted that he was fit enough to carry on playing.
However, Bielsa decided against risking Roberts, and took him off for Helder Costa.
“He felt something in some muscle,” Bielsa explained. “He wanted to continue, but we thought that was risky and we prefer to substitute him.”
Bielsa’s substitute ended up working well for Leeds, as it was Costa who set-up Jack Harrison’s dramatic late winner.
The Whites had been the better side for much of the contest, but couldn’t find a way through the Reading backline.
However, Harrison eventually managed to sneak home at the back post and head home a cross from Costa in the last minute to put Leeds back to the top of the Championship table.
Leeds are next in action against Middlesbrough at Elland Road on Saturday.
