Celtic have announced the signing of highly rated 24-year-old, Boli Bolingoli-Mbombo.

The Belgian, who can play as a winger, agreed to team up with Neil Lennon’s side after two seasons with Rapid Vienna. Celtic took to Twitter to announce their third signing of the summer – after Christopher Jullien and Luca Connell.

The left-back has joined for a fee of around £3 million on a four year deal, which has furthered the speculation that Kieran Tierney could depart the club this summer.

This could be a case of the writing being on the wall for the Celtic support as it would appear that Celtic have sought after and acquired a left back to replace Tierney; albeit if the interest in the 22-year-old manifests itself into an offer deemed acceptable by the club.
