Man Utd's Brown two games from glory
He said: "This is one of my best seasons. I have played every week when in other years I have been in and out of the side.
"It is great to be doing that and hopefully I can keep the run going. Two more wins would bring two trophies so that would be brilliant.
"We have played well in the league all season and to throw it away now would be very disappointing.
"To get to the Champions League Final is a great achievement for everyone at the club. We are there now but we know we still have not won anything."
Brown has also singled out Cristiano Ronaldo for praise as the season reaches a thrilling climax.
The Portugal international winger took his tally to 40 goals - 30 of them coming in the league - in the 4-1 victory against West Ham.
"Cristiano has been unbelievable, especially considering he is playing on the wing as well," Brown added.
"He got us started against West Ham and from that moment, we never really looked as though we would get beaten."
