Steve Cotterill paid tribute to David Cotterill’s wing wizardry as the loanee got set to see the season out at Pompey.
The Wales international is close to agreeing a deal to remain on loan at Fratton Park from Swansea for the rest of the campaign.
Blues boss Cotterill has held talks with Swans manager Brendan Rodgers, who has given the green light for the move to take place.
He said: ‘I’ve spoken to Brendan earlier in the week and he seems okay with us extending that to the end of the season.
‘Hopefully that can be done in the coming days, so now it’s over to the people who do the paperwork to do that.
‘Hopefully that can be done. We just wouldn’t want a 24-hour recall.
‘That wouldn’t be something we’d follow up and go through with in that case.’
Cotterill has been delighted with his namesake’s displays and the manner in which he has settled at the club.
He feels the 23-year-old’s trickery and ability gives his side an ingredient they didn’t have at their disposal.
Steve Cotterill said: ‘I think he’s done very well for us, I’ve been very pleased with him.
‘I think his last couple of games haven’t been as good as his first couple. I think he’d say that.
‘He gives us good width in the team. He plays different out there to how Liam Lawrence plays. That, perhaps, has helped Ritchie de Laet a bit.
‘He keeps his width which we’re pleased about. He’s not your big right winger who will jump up at the far post and win headers.
‘But I think he’s been like the other boys. He’s come in and mixed with them, and settled in very well.’
