When fighting for survival in the Premier League, having a clinical goalscorer can be the difference between staying up or going down.
Fortunately for Watford, they have one of the most in-form forwards in the top flight this season - Emmanuel Dennis.
And even more fortunate for the Hornets, an administrative error means they have not lost the Nigeria international to the Africa Cup of Nations this month.
That means he will be available for some crucial fixtures against Watford's relegation rivals, including Newcastle on Saturday.
So just how big a difference could Dennis make in the battle to stay in the Premier League?
