Watford must get a better result than Aston Villa so will be keeping eyes on developments at the London Stadium.
The Hornets’ goal difference is worse than Villa’s by one but have scored significantly fewer goals so would need a two-goal swing if both teams end on the same points.
Watford interim boss Hayden Mullins does not want to see his outfit going all-out in attack, however.
“We need to be a threat to their goal, definitely, but I don’t think we can be all-out attack, gung-ho,” he said.
“I think we have to try to be as balanced as we can. There could be a number of different things happening on Sunday and I’m sure in one five minutes the table will look different to the other. We need to stay focused on the pitch, focused on what we’re trying to do.
“Once the players cross the line and the game starts, as a professional player a lot of the emotion and what’s going on outside of the game goes away, and you start to focus on your job professionally, both in and out of possession and your set plays. There’s so much going on on the pitch, it’s hard to focus on what might be going on off it.”
