Leeds United drew 1-1 with Wigan Athletic in Championship action yesterday.
Monk had suggested earlier in the week that Berardi would be involved for Leeds against Wigan.
However, he was not put in the 18 man squad which faced the Latics, leading to questions being asked of why the full-back as not involved.
Berardi was one of Leeds’ most impressive performers last term, but it appears that he still has work to do to break back into the Whites’ starting line-up this time around.
“Bera understands the situation,” Monk said. “He’s training hard. You have an 18 man squad to pick and you have to pick the ones in the right shape and condition.
“Bera will be in the squad when he deserves to be in the squad.”
In Berardi’s absence Leeds could only manage to pick up a 1-1 draw against Wigan.
Berardi could now make his return to action in Leeds’ next match, which comes against Wolverhampton Wanderers on Saturday.
Luke Ayling has been covering for Berardi while the Swiss defender has been out injured, and the former Bristol City man has generally impressed with his performances.
