Guy Whittingham saluted Pompey’s return to form - and ruled himself out of the running to replace Steve Cotterill.
The first-team coach and Stuart Gray took charge of the Blues for the visit of Barnsley.
The team responded with a 2-0 Fratton Park triumph, David Norris and Luke Varney getting the second-half goals.
Whittingham and Gray are now likely to oversee the team for the next two fixtures against Ipswich and Doncaster at the very least.
But the Pompey legend revealed he has no intention of taking it on a permanent basis.
He said: ‘I don’t want the job, definitely, I can say that.
‘I’m quite happy being a coach and spending time with my family. The same goes for Stuart.
‘We played well tonight, the lads responded well and all credit for them doing that.
‘But this is not something I want to keep on doing permanently.’
