The Belgian youngster smashed only his second-ever goal for the Reds during the 2-1 reverse to Arsenal and has started to look at home in midfield at this level after graduating from the youth team.
"It was a great strike and I think he's played really well for the last few weeks now," Joyce told MUTV. "His determination in midfield in wanting to tackle, sniff out danger and put himself around for the team has been fantastic.
"A quality moment like that can only give him confidence."
Ekangamene survived a late challenge by Arsenal's matchwinner Hector Bellerin at the end of the match which could have placed his involvement in the Dallas Cup under threat.
"It looked a poor tackle to say the least," added Joyce. "I'm just glad he's okay."
