The Blues will now face off against Manchester United for the national title, which they won last season. And Morris is delighted with the outcome.
"We were electric in the first half," he reflected after the game.
"I thought we played some great stuff, lovely passages of play and interchanging but also really good off the ball as well. We said to the players at half-time that if we could get anywhere near that level in the second half, it should be a decent score.
"It was a little disappointing to concede because I didn't think it was a foul at all for their free-kick but overall it was a really good performance, especially in the first half. There were some great individual performances but as a collective I thought we were great. I'm extremely pleased and proud.
"The boys have grown as the season has gone on, not only improving individually but getting better playing in different formations and with different game plans. The run we're currently on of 15 wins in a row is just outstanding but it's testament to the levels we've been consistently hitting.
"Although the lads constantly have myself and Ed [Brand, Under-18s assistant] trying to motivate, demand and test them, they're also incredibly demanding of themselves. I think they like the fact we let them know little milestones or records that they're breaking, or getting close to breaking, and they like to chase that which is a good winning mentality to have.
"I always feel the best teams win the leagues. In a cup competition, anything can happen and you can always get knocked out with an off day, but the league is the measure of you as a team in that season. Arsenal and Southampton have been great in the southern league this season, especially after the first couple of games, so it shows the level we've played at for us to win the title with two games to spare. The boys thoroughly deserve it and all the accolades that will come with it."
