The 23-year old Colombian started yesterday's 2-1 win over Real Salt Lake on the bench before coming on for the final 20 minutes.
Last season Montero starred for the Sounders but so far this campaign he has failed to deliver. He accepts that and is prepared to work hard so he can get back to his best.
"As players we don't like to be on the bench, but it's a technical decision. I just have to grit my teeth and support the team," he said through a translator.
"We're all human beings. We're not perfect. Sometimes we have good and bad moments and I hope that my play from now on will be (better)."
But away from the individual side of things and Montero was delighted that the sounders were able to come away with all three points.
"It was a very big moment for the team. To (have the home record) that this team had for two years is not easy. We came over, played an intelligent game, scored two goals and got the three points," he added.
