Stephen Henderson targeted two wins on the bounce to get Pompey’s season firing.
The Blues keeper believes his team is capable of delivering successive maximums to propel them up the Championship table.
Steve Cotterill has found himself coming in for flak from some quarters after picking up one win in seven.
Henderson is adamant it is the players who should be putting their hands up and taking the blame, though.
The 23-year-old came in for his Pompey league debut last time out, but could not stop a 1-0 defeat at Leeds.
But Henderson promises no-one at the club is pressing the panic button.
He feels three points against Barnsley on Saturday, followed by a win on the road at Ipswich, will get his team upwardly mobile.
Pompey currently sit in 19th spot on nine points and know they can ill-afford to let a gap open up with the early-season pacesetters.
But Henderson says there is the conviction in the camp that the team can turn things around.
He said: ‘I’m sure I speak for everyone when I say the players take responsibility for recent results.
‘The manager sets it all up for us so we know what we’re doing. So to give away a sloppy set piece, like we did at Leeds, is unprofessional.
‘So we take full responsibility as players for that.
‘I’ve seen every game this season and we deserve more points. No-one is panicking, though.
‘Two wins and we’ll be right back in there.
‘We’ve got the manager to get us in there. He does everything that he needs to do for us.
‘We are fully behind Steve and Steve is fully behind us.’
