Celtic have completed the signing of midfielder Youssouf Mulumbu on a two-year contract.
Former West Brom and Norwich player Mulumbu, 31, was a free agent after a spell at Kilmarnock last season.
The Scottish champions are also close to completing a loan deal for Leicester City defender Filip Benkovic, 21.
And manager Brendan Rodgers hopes to retain Moussa Dembele, 22, after Celtic rejected a "significant" bid for the striker.
France Under-21 cap Dembele has been the subject of transfer interest from Lyon and did not play as Celtic booked their place in the Europa League group stage with a 3-0 defeat of Suduva.
Mulumbu's only goal during his 20 games with Killie was in a 1-0 win against Celtic and the former Paris St-Germain player has made more than 300 club appearances.
