Grant clearly gets the vote despite only being on the pitch for the last 30 minutes. Although the Imps had the lion's share of possession, the inexperienced midfield was struggling to impose any sort of control and bring the front 3 into play, in the second half in particular.
That all changed once Grant came on, he started to control the game and immediately a tiring Scunthorpe were in trouble. Credit also to Jones who's energy and experience helped build that control and created more of a threat.
