Mitrovic scores 5th EPL goal as Fulham draws with Watford
The visitors then wasted a string of chances before Luciano Vietto beat Daryl Janmaat on the left and squared for Mitrovic to prod the ball in at the near post after 78 minutes.
Fulham manager Slavisa Jokanovic, facing his former club for the first time since leaving Watford in 2015, almost saw his side snatch a late winner when Mitrovic's header was tipped on to the crossbar by Ben Foster.
"They had many chances in the first 45 minutes. I was not satisfied," Jokanovic said after his team avoided its fourth league defeat of the season.
"We didn't have confidence in our game. When we found a better attitude and pushed together we played our best and scored the goal."
