The young Leeds United forward currently plays for their under-21s.
The 19-year-old is regarded as one of the best young strikers coming through the ranks at Leeds right now and he has been impressing at under-21 level this season.
That said Blunt feels there is still plenty for the young Irishman to work on before he can be challenging for a first-team spot at Elland Road.
Speaking after Leeds’ second under-21 game in quick succession – a 0-0 draw with Birmingham City – Blunt told BBC Radio Leeds that while Mulhern has innate talent he has to get smarter in his overall game to ultimately succeed.
“Frank has got bags of potential but we would probably like to see him a bit more consistent with his performances,” Blunt said. “He has got that over the last six months; he has become more consistent in his training. But there’s ability there, he is quite raw, quite different, he has just got to tidy the game up.”
Comparing Mulhern to another young Leeds forward, Malik Wilks, Blunt said, “Sometimes they take two or three on, but then sometimes you’ve got to look how often they retain possession for the team and I think the higher they go, they might not get away with it.”
They are wise words and the Leeds pair will surely take them on board as they bid for new contracts and ultimately a shot at the Whites’ first-team.
This summer they may travel with the senior side for pre-season training and if so it will be a great opportunity to show manager Steve Evans how far they have come.
