The Spaniard has backed Remi Garde's decision to demote one of his star men.
The attacking midfielder has been dropped from the first team squad for this weekend’s game, after off the field activities following last weekend’s loss to Everton.
The 20-year-old was pictured partying with friends following that 4-0 defeat, and as such has been banished to train with the Under 21’s at the club’s training ground, Bodymoor Heath.
It is the first big decision Garde has had to make of his short reign at Villa Park, and Flores feels the Frenchman got it right.
"I realise he's important for Aston Villa - when he's playing it's a very different team but I understand the decision of the coach," he told Sky Sports.
“When someone miss-trains out of the profession, the behaviour of the players is not of the best behaviour representing the club. Sometimes these younger players they need to make mistakes and they need to learn about these mistakes."
Given Grealish’s past indiscretions, demoting him this time was the right decision from Garde.
It is a risky one from the Frenchman, though, with the decision sure to have upset Grealish, who is very much one of the key players at Villa Park.
Losing him would be a big blow to the side, who are going to need him firing on all cylinders as they try desperately to avoid relegation once again this season.
They will then be hoping he takes this demotion as a chance to prove himself then, rather than as a reason to down tools, or worse, seek an exit down the line.
