The 38-year old Australian veteran has been in brilliant form yet again this term as the Cottagers have returned to the top half of the table with improved results in recent weeks.
On Saturday, Fulham backed up their midweek home win over Bolton with a 3-0 victory at Sunderland and although at times it was a little messy, Schwarzer said it was the type of performance which showed how far the London club has come this season.
“Saturday was a good win and a good performance from the team," Schwarzer told fulhamfc.com.
"We perhaps got a little sloppy in the first-half and let our concentration slip at times but fortunately they [Sunderland] couldn’t capitalise.
“But overall we responded very well, after a nice goal from Gael Kakuta and from a few strong words from the Manager (Mark Hughes) at half-time. He wanted us to improve on that first 45 minutes and we did – which was important.
“The second-half was very professional and the effort from the players was rewarded with two more goals. It was nice to get that away win, as everyone knows we haven’t picked up as many points as we hoped or should have away from home.
“But this was a performance that shows the progress that we are making and that’s good to see.”
