Bruno Fernandes says winning this season's Europa League is not enough for a club of the stature of Manchester United.
The Portugal attacker scored twice in last week's 6-2 semi-final first-leg victory against Roma at Old Trafford and they're set to seal a place in the final tonight.
Fernandes says they're determined to go on and lift the trophy in Gdansk last this month, but he believes United need to set their standards higher next term.
"For us, it is a signal of improvement if we win the Europa League, because last season we didn't win anything. So, if we win a trophy this season it is an improvement - but still not enough for us," he said.
"But it is something growing up from the club. From the players, it is a sign that we are doing a little bit better, but we have still a lot to improve on as I said before, and we will improve.
"Honestly, for me when you play a club like this your standard has to be high.
"For me, the game against Roma was not my best, but of course on numbers, everyone will say it is the best one I have done because the two goals and two assists I think was the first time I did it for the club, but of course it was a good game.
"I think also individually I played really well but I want to improve. I want to improve so I have to do maybe next time two assists and two goals, or three goals and two assists to improve again, but the most important for me is the way we win and we are closer to getting the trophy."
