Maghoma struggled for consistency during his two years at Hillsborough and was often a source of frustration for many match-goers.
However, he appears to be thriving at St. Andrew's, after reuniting with his former Burton Albion boss Gary Rowett in the summer.
Together, they've helped the Blues to seventh in the Championship, and after beating Hull City 1-0 on Thursday, they're only a point behind Maghoma's old club Wednesday, who occupy the final play-off spot.
The winger has contributed four goals and two assists so far this season, and Rowett last week admitted that the club were keen to tie him to a new deal as a reward for his recent form.
But for many Blues, Owls and others on Twitter, Maghoma's form did not extend into Thursday night:

Maghoma must have completed about 3 passes all evening. Pretty dire. Massive result though if it happens. Advantage Boro #borolive— Paul Ronald Wilson (@paul_wilson22) 3 March 2016
Maghoma tasted defeat in both his matches against Wednesday this season, but could yet have the last laugh, with 12 games left to play.
On Thursday, the 28-year-old was called up to the DR Congo squad for this month's African Cup of Nations qualifiers against Luanda.
