Sevilla are still keen to sign Dedryck Boyata.
The defender is out of contract at the end of the season and has endured a dramatic fortnight after Celtic rejected a £9m offer from Fulham.
After self certifying an injury he appears to be back in the fold after taking part in training over the last two days.
“Boyata is one of those players that we have been following for a long time,” he told The Sun. “Defence is an area we need to reinforce.
“We must proceed calmly because there are many factors with a transfer that doesn’t just depend on ourselves.
“The squad is balanced and impressive, but maybe there is something missing and we will try to address that.”
Boyata is likely to be in the Celtic squad that travels to Lithuania tomorrow for the Europa League qualifier against Suduva.
After contradicting his injury claim Brendan Rodgers has a major balancing act on his hands to resolve the situation with ten days left in the transfer window.
Celtic are believed to have opened talks with Aberdeen to sign Scott McKenna with a figure in the region of £2.5m likely to get business completed.
