Neil Lennon is considering switching Niall McGinn to right-back after the winger performed well in defence during Celtic's friendly defeat by AZ Alkmaar.
"He played there in a development game against Queen of the south and he was excellent," said Celtic's caretaker.
"And you saw his quality when he ran through the Alkmaar defence. It is an option for us."
Georgios Samaras gave Celtic the lead, but Graziano Pelle equalised and Jonathas scored from the penalty spot.
Celtic had fielded a second-string side against the Dutch side, giving fringe players a run out and introducing three young players - goalkeeper Dominic Cervi, defender Blair Tolmie and right winger Paul George.
Only 3000 fans, nearly half the number that watched Celtic defeat Rangers 2-0 to win the Scottish Youth Cup final along the road at Hampden Park, turned up at Celtic Park for the friendly.
I asked them to prove me wrong and some of them are doing that and that's all I can ask
Celtic interim manager Neil Lennon
But Lennon thought it was a beneficial outing and was satisfied with the display in a game that had been delayed for a week because of the Icelandic volcano disruption of flights.
"I'm really pleased with the players," he said after the match at which Wolves manager Mick McCarthy was interested spectator.
"The game was a bit of a godsend. It was against quality opposition who played a different style of football.
"I'm concentrating on the league games, but tonight was a wee bonus for me in terms of some of the performances.
"It was a really worthwhile exercise and hopefully they have learned something from that."
Samaras shot the home side into the lead after 39 minutes against the team managed by former Rangers boss Dick Advocaat, but Pelle levelled for the visitors three minutes later.
In the 74th minute, Alkmaar substitute Jonathas scored from the spot after Celtic left-back Edson Braafheid had handled in the box and, although the home side fashioned plenty of chances, they could not draw level.
"We looked comfortable and created a lot of good chances and a lot of the players have given me food for thought," said Lennon.
"A lot of these players haven't played for a while and so it was good for them to get out and play against quality opposition and they did themselves no harm."
Lennon has been pleased with the way that Celtic's players have responded after their surprise defeat to First Division opposition in the Scottish Cup semi-final.
"After losing to Ross County, I asked them to prove me wrong and some of them are doing that and that's all I can ask," he said.
Ki Sung Yueng impressed for Celtic and Lennon said that the South Korea midfielder would be given more opportunities to gain match fitness ahead of the World Cup.
Lennon is also giving some of his victorious youth cup squad first-team chances before the end of the season.
