Ironically enough, 'Jacko' could be the man to profit most from Paul's return to Charlton after Alan Curbishley recalled him from his loan spell at the Lane.
That led to David Pleat calling back John and Stephen Kelly from loans at Coventry and Watford respectively and both have now made their Premiership debuts.
Jacko took his bow at Portsmouth and followed up with a man of the match display against Charlton at the Lane.
Paul, who did so well for us down the left flank in 15 appearances on loan, is impressed with what he's seen of Jacko.
"The fans got right behind Jacko and he did really well," said Paul after playing for Charlton against us on Sunday. "Hopefully he'll carry that on.
"One thing's for sure - if he produces crosses like he did throughout that game the boys will get on the end of them.
"It's just a matter of playing games for him. He started well and more games will give him confidence and belief on the pitch.
"He's done it in two games and I'm sure, given the chance, he can do it for the rest of the season."
Paul Konchesky believes John Jackson has what it takes to be a Premiership hit for the rest of the season.
