Barcelona’s 3-2 win over Real Madrid in the Spanish Super Cup secured Rashford’s first piece of silverware with the club, thanks to goals from Raphina and Robert Lewandowski.
Speaking to club media after the final whistle, Rashford praised his side who he hopes will go on to more success this season as they eye the title and Champions League.
"Very happy today. It's always the best feeling to win the first trophy," Rashford beamed. "I hope now for the rest of the season we can go on to win some more."
"It was a top performance. This is what we are capable of doing. There are still things to improve, like always, but today we enjoy this performance."
Barcelona have an option to make Rashford's move permanent at the end of the season for a fee of around £26M and if he helps the side to another piece of silverware then the Spanish side may seriously consider keeping him once the season ends.
When asked if this will be his first and last trophy with the club, he said: "I hope not.
"It's really good. When we win it makes it so much easier but I feel like throughout the season, even in moments we're not playing so well, we stick together and act as a team. So, for me it's perfect. I'm really enjoying my time here."
The England star has started 12 times in LaLiga under boss Hansi Flick this season, playing 1114 minutes so far. Flick will have him in his plans going forward as long as he keeps his performances up.
