Northern Ireland legend Pat Jennings hopes Michael O'Neill's successor keeps Jimmy Nicholl in the senior international set-up.
Former Manchester United defender Nicholl, who won 73 caps and starred at the 1982 and 1986 World Cups, joined O'Neill's backroom staff in 2015 and proved to be a popular figure with the players as the team reached Euro 2016.
He was also O'Neill's assistant as Northern Ireland reached the 2018 World Cup play-offs and secured a play-off semi-final clash against Bosnia and Herzegovina for next summer's delayed Euro 2020 tournament.
Stoke City boss O'Neill has hailed Nicholl as a key driver behind Northern Ireland's resurgence during his time as national boss and Jennings feels the new man in charge shouldn't simply overlook the vastly experienced and popular 63-year-old.
"Jimmy Nic has been a big part of the team and I would hope that whoever gets the job will keep Jimmy as part of the set-up," said Jennings, still his country's record appearance holder with 119 caps, though Steven Davis is just behind on 117.
"You just can't discard what he knows about the team. Like Michael he got to know the players inside out and I think it's important that someone like him is not discarded.
"Not to use someone with that knowledge would be a shame but I'm not sure what the Irish FA and Jimmy's plans are."
Northern Ireland will have a new boss calling the shots when they return to action in the Nations League in Romania on September 4, before hosting Norway three days later.
If O'Neill's successor is appointed by the middle of August, as the Irish FA have suggested, the new Northern Ireland manager could have less than one month to prepare for his first game in charge.
The leading contenders to succeed O'Neill are thought to be Northern Ireland Under-21 manager Ian Baraclough, Motherwell boss Stephen Robinson, currently preparing for his club's August return to action in the new Scottish Premiership season and Tommy Wright, who left the hotseat at St Johnstone in May and is now being linked with the vacant manager's job at Dundee United.

"It was a pity Michael left for Stoke City but it was surprising he stayed with us for so long," added the former Spurs and Arsenal stopper.
"He's done such a fantastic job and you can understand his desire to give the club game a go. Hopefully whoever comes in can keep the team moving forward.
"Michael was meticulous and believed in bringing young players through.
"I worked with Tommy before but don't really know Ian or Stephen but they have experience of working with the players and that is valuable.
"It's just unfortunate to lose Michael when we had a chance to qualify for the Euros again. It would have been nice for him to take us there.
"It will be interesting to see how the new manager does because it will be a different personality and way of doing things. I worked with Danny Blanchflower before Billy (Bingham). Danny was a lovely bloke who loved the underdog but his philosophy was we are boring people to tears losing 1-0 and 2-0.
"He said let's go out and lose 5-4 and I'm sitting there with a reputation of being one of the best goalkeepers in the country thinking, 'I'm going to concede five!' Then I'm thinking, 'How are we going to score four?!'
"Under Billy we got clean sheets and started winning."
