Jed Wallace threw his weight behind Guy Whittingham and vowed: We need to repay his faith.
The midfielder promised there was a burning desire to put the York debacle right against Rochdale this weekend.
Pompey served up one of their worst displays in recent times as they fell to a shocking 4-2 defeat at Bootham Crescent on Saturday.
That has seen frustrations at a lacklustre start to the season mount, as Whittingham’s side fell to 17th in the League Two table.
Wallace feels the onus lies with the players, though, and not just the manager to make improvements.
The 19-year-old knows he is indebted to Whittingham for giving him his chance in the first team.
And he made it clear he and his team-mates are gunning to show why the Blues boss gave them their opportunities at Fratton Park.
Wallace said: ‘The manager gave me my chance and I appreciate that.
‘If Michael Appleton was still here I don’t think I would have been playing.
‘That’s no disrespect to him, obviously. That’s just the way it is.
‘So I’ll stick by the manager – as do all the rest of the squad who are here. There’s no problem with that.
‘From my point of view, this is a new group of players.
‘The manager, along with the board, has given a lot of these players a massive opportunity.
‘These players were free agents and he’s given them a chance. He’s given us support.
‘Sometimes you need a kick up the backside.
‘I can tell you everybody will be running twice as hard on Saturday. I can tell you that.’
Saturday’s loss made it a single league win in the past six games for Pompey ahead of the meeting with Rochdale.
Wallace knows the Blues’ current form is not good enough but feels there’s the quality in the dressing room to put it right.
Pompey found themselves fall into a terrible run of form last season in League One as the club was blighted with problems.
Wallace feels there will be no repeat of that in this campaign, though, with a squad of players in place with the passion to improve the club’s fortunes.
And that determination will be key in putting the wrongs at York right.
Wallace said: ‘There’s no reason why we can’t win the next six games.
‘Then it will look like we’ve had a good start to the season.
‘The manager will feel gutted and we’re looking around at each other in the dressing room and we’re devastated. We’ve let everyone down.
‘The difference this year is that we care. At times last year we’d lose and you’d go in the dressing room and no-one cared.
‘The difference is this year we have a group of players who care about the club.
‘We will do everything in our power to put it right.’
