Carabao cup final loss gave villa a lot of belief grealish

I think there may be a bit of a misunderstanding here!

The Carabao Cup is a domestic cup competition in English football, and the final is played between the winners of the two semi-finals. Aston Villa did not win the Carabao Cup, so it's unlikely that a loss in the final would have given them a lot of belief.

However, Jack Grealish is a talented English professional footballer who plays as an attacking midfielder for Aston Villa and the England national team. He has been a key player for Villa and has helped the team achieve some impressive results, including a promotion to the Premier League in 2019.

If you're referring to a specific match or period in Aston Villa's history, could you please provide more context or clarify what you mean by "a lot of belief"? I'd be happy to try and help you understand the situation better!
