@DavidHindmarsh7: “Exactly why we should be playing 3 at the back with all these injuries. O’Nien has been great but there was always this threat.”
@danhall94: “I like Leadbitter as a person but as a player he’s too slow! Give him a coaching role or something.”
@Philip_RJ89: “Let’s not hang O’Nien out to dry. Yes, that was a costly error, but it’s the first real mistake he’s made since he’s been moved into defence. Scapegoating one player is daft.”
@ConnorGardner: “How refreshing is it having a manager that makes effective substitutes to try and win the game?”
@SAFCSpencer: “Huge opportunity missed. Don’t like the 4-3-3.”
@GoochGlorious: “They didn't deserve that. We should have had penalties”
@JamieSAFC_: “Nothing changed in the top 6 so can't feel too bad tbh.”
@PlannerMarj: “One game too far perhaps. The lads must be exhausted.”
Collings1995:” Can't argue with it. Lincoln played well. We played well in spells. Ref had an absolute mare and should never be an official ever again.
@theboovont: Wrong starting line up, power and Leadbitter have no pace in cm, looked very leggy, only one team looked like winning it in second half
