Guy Whittingham is refusing to rush a new deal for Jed Wallace.
And the Pompey boss told the midfielder he can expect a period out of the starting XI as he continues his football development.
Whittingham is keen to see the promising teenager pen an extension to his current deal which ends in the summer.
But he feels a desire on all sides to come to an agreement is more important than pursuing a conclusion to talks.
Wallace has started every game so far this season going into today’s clash with Morecambe.
His form has not hit the heights of his emergence last season but Whittingham feels the 19-year-old has to lessen the pressure he puts on himself.
The Blues manager underlined the fact he sees Wallace as a big part of the club’s future.
Whittingham said: ‘It’s important to have your own players who have come up through the club –and Jed is one of those.
‘We think very highly of him and he wants to be here, so hopefully we can get something sorted out.
‘I don’t think it’s something we have to put a deadline on, though
‘Jed is enjoying his football, wants to be a big part of things – and we want him to be a big part of what we are going to do.
‘There is no mad rush to get it done.
‘It’s a case of all sides promising that is the best thing to do.
‘He was new on the scene last year and everyone was seeing this energetic kid run around.
‘People were seeing him charge around at 100mph and it was a breath of fresh air sometimes.
‘When Jed gets a decision wrong he berates himself. He will have to realise those things are going to happen, deal with it and not worry about the pressure it brings.
‘It’s a learning process. All of these kids have to realise they’ve got a future in the game.
‘But a new group of players have come in and he has to get used to them and they to him.’
Whittingham took Dan Butler out of the firing line last weekend following an extended period of first-team football after making his Blues breakthrough last season.
He admitted Wallace can expect the same, with competition from the likes of Ricky Holmes following his recovery from a foot injury.
‘There will be competition for places and Jed’s in the mix with them,’ said Whittingham.
‘Jed is in the team at the minute but we have Ricky Holmes champing at the bit to get on because he hasn’t played since January.
‘He desperately wanted to come to this club. If he hadn’t been out for that week it could have been him starting and Jed on the bench.
‘It was close between a lot of them.
‘Jed will have his time when he is out of the team, like Dan Butler.
‘It could be at least 15 years in the game for him, so he will have plenty of time to shine.
‘We have to make decisions on who’s starting or not and the ones who aren’t have to realise there are some good players here.’
