Manchester City boss Pep Guardiola wants his side to use their Carabao Cup victory to spur them on to Premier League and Champions League glory.
City won the League Cup for a fourth successive year and joint record eighth time in total with a 1-0 win over Tottenham at Wembley on Sunday, which came courtesy of Aymeric Laporte's late header.
Guardiola's side do not get much time to bask in their latest glory, though, as they meet Paris St Germain in the Champions League semi-final first leg on Wednesday, while Manchester United's draw with Leeds on Sunday moved them closer to another league title.
"Pain. It hurts. I've been sitting in there as a player, I've played for this football club and lost a final, I know what it's like," said Mason.
"I know that feeling. It's normal that they're hurting. It's normal, because it shows that they care.
"And this group of players care deeply about this football club. I think we saw that today, they gave absolutely everything, 100 per cent commitment. We tried, we tried, it wasn't enough today, that's tough to take.
"City are a great side, an incredible team but I think our group of players gave everything with what they have had to deal with in seven days, the lack of preparation but they gave everything, absolutely everything. That is something to be proud of.
"I think when you lose a cup final, it's disappointing. We're all hurting. I am, the players are and I'm sure the fans are and everyone associated with the football club. It's difficult to take. Obviously it's my job, a coach's job to start giving the players a platform and start preparing, start planning."
