Evans said: “We’ll look at a change of personnel and also a change of system because we need to find a way of catching them out. We need to do what we did to Middlesbrough and get on the front foot straight away. I don’t want to give Watford the benefit of predicting what we’ll do.”
Evans alternated his usual formation against Boro on Monday, utilising Stuart Dallas as a more central player rather than on the wing, and it seemed to cause Aitor Karanka’s men problems.
Despite their impressive form over the seasons, Boro struggled to deal with the system change, with Leeds playing in something of a 4-3-2-1 formation.
This is different from how they have played for much of the season, and it proved successful, meaning Evans could again utilise the system this weekend, as the Whites head to Vicarage Road to take on Watford.
Both teams are looking to continue their fine FA Cup runs, and Watford will undoubtedly be favourites, but Evans could look to change the personnel and the system to keep the Hornets guessing until the game starts.
Leeds best chance of success will come from surprising Watford, and if they can start the game strongly, they could just cause an upset at Vicarage Road.
