Neil Lennon has explained Marian Shved's continued absence as he urged the sidelined winger to give him more.
The Ukrainian, a £2million January buy from Karpaty Lviv, arrived at Celtic this summer after spending the rest of the season back on loan with his former club.
But he's made only one fleeting competitive appearance - a late goalscoring cameo against Nomme Kalju in Champions League qualifying - and was left out entirely during Thursday night's win over AIK.
Some fans have been left baffled by Shved's lack of minutes, having arrived to much hype amid tantalising footage of the 21-year-old in action back in his homeland.
Lennon revealed Shved is still adapting to life in Scotland and backed him to emerge as the season continues.
"A little bit frustrated, he just needs to up his tempo and his work," the Celtic boss said.
"It's still, again, an adaptation period for him. He's 21, in a new country and doesn't speak great English.
"So, we know we've got a good player on our hands and we'll see more of him as the season progresses."
Meanwhile, Celtic have made their move to sign Kilmarnock defender Greg Taylor .
He's been earmarked to provide competition to Boli Bolingoli at left-back following Kieran Tierney's departure.
Record Sport understands the Hoops approached Killie on Thursday and were told he's valued at £3million.
There's genuine interest from the Premiership champions but they are reluctant to meet the figure quoted.
Taylor is believed to be keen on the move and an offer could be made over the next 48 hours.
