Heart of Midlothian's set-piece coach Ross Grant has joined Celtic, a move that could prove to be the club's most significant signing this summer.

What makes Grant's signing important?

Grant spent four years at Dundee United before enjoying a successful 12-month spell at Heart of Midlothian. His impact at Heart of Midlothian was significant, with the team scoring more than a third of their league goals from set-plays.

How did Grant's set-piece strategy work at Heart of Midlothian?

Heart of Midlothian's set-piece record was impressive, with 23 goals coming from set-plays, a league high. Sixteen of those goals came from corners, with striker Claudio Braga and centre-back Stuart Findlay scoring five headed goals each.

What can Celtic expect from Grant's expertise?

Celtic manager Martin O'Neill has expressed his excitement about working with Grant, who will have a particular focus on set-piece analysis and coaching. With Grant on board, Celtic will be looking to improve their own set-piece record, which was mid-table last season. | Set-Piece Goals | Team | | --- | --- | | 23 | Heart of Midlothian | | 13 | Celtic |

How will Grant's signing affect Heart of Midlothian?

Heart of Midlothian will be looking to replace Grant's expertise, having relied heavily on his set-piece strategy last season. The team's defensive record from set-pieces was also impressive, with only two teams conceding fewer goals from set-pieces than Heart of Midlothian. As the new season approaches, Heart of Midlothian will be looking to maintain their set-piece prowess without Grant's guidance.
