But red card problems have undermined Gerrard's first campaign with goalkeeper Allan McGregor receiving their 12th dismissal of the season during Sunday's 1-0 win over Hibernian.

Jack admitted he had seriously reflected on his behaviour last summer and believes the squad need to do the same after Gerrard admitted he was running out of ideas to tackle the problem.

"Firstly you take what comes with it and there was obviously a lot of talk about it and you get a lot of stick and criticism, and you let your team-mates down, you let your fans and manager down," Jack said.

"I kind of just reflected and said 'this needs to stop, I can't be letting my team-mates down first and foremost, they are the ones that have to play with 10 men'.

"I have kept my discipline and as a squad that's what we need to do.

"It has cost us this season, missing key players at key times, and if we don't rectify it we will be in the exact same situation next season.

"We are the players, we need to take responsibility for our actions on the pitch.

"We have to reflect on it and maybe as a squad sit down and say it's costing us and we need to sort it out."
