The manager praised his squad's mindset during the final weeks of the season.
"It's not ended here and I think we want to keep building and keep pushing.
That's credit to the players, it's not easy to do it as much as we'd expected and hoped for it.
I've been there and it's not easy to find that spark," Carrick said.
He noted the challenging weather conditions and opponent's style tested the players' stamina.
"But the hunger was there, you could see it and it was probably the toughest team to play that type of game in the heat, the way they move the ball.

So it needed a really strong mentality, which I was absolutely delighted with because that's the foundation we need to show and have to give us the confidence to move forward," Carrick added.
