Manchester United defender Teden Mengi declared his debut was "just the start" after featuring in the club's 2-1 Europa League win over LASK.
Mengi, 18, replaced Timothy Fosu-Mensah with six minutes remaining on Wednesday night and didn't look out of place under the bright lights of Old Trafford.
The promising centre-back savoured his first chance to impress Ole Gunnar Solskjaer and seems intent to continue making progress at the club.
"It's a great feeling. I'd like to thank everyone around me. My family, my teammates and everyone in the first-team made it very easy for me," Mengi told MUTV after making his debut.
