I want to be enjoying it as long as I can compete at this level but you can never put a time limit on it because you never know what is around the corner but if I keep feeling like I am at the moment then I will be looking to play for a few more years yet." By late–December, he was dropped from the substitute bench, with Hennessey preferred as the club's first choice goalkeeper for the rest of the 2017–18 season.

Under the new management of Tony Pulis, the club's results soon improved in the league as the 2013–14 season progressed.

In a match against Burnley on 13 September 2014, he saved a penalty from Scott Arfield, as the club drew 0–0. After the match, his performance was praised by the returning manager Neil Warnock, saying: "I think they broke the mould with him.

Teams in Italy were interested in me but I decided to stay at Dundee, and now, even though I am still only 24 years old, I am playing the biggest game of my career."
