Celtic may have won every domestic competition for more than three years but that doesn't mean that every one of their signings has been a success.

One man who failed to live up to expectation was Youssouf Mulumbu. The midfielder arrived in 2018 with a wealth of Premier League experience and had impressed Brendan Rodgers at Kilmarnock the season before, yet he went on to make just three appearances for the Bhoys.

In fact, it didn't take long for Neil Lennon to get rid of him altogether when he returned to the club in January 2019, and that says a lot about the lack of contribution he made during his spell.

Many fans were pleased with his arrival, however, which makes his limited impact even more disappointing, and suggests that fans' views shouldn't always be trusted when it comes to new additions.
