Manchester United youngster Alejandro Garnacho was keen to praise his teammate Kobbie Mainoo after their FA Cup win over Reading.
The young duo came off the bench in the second half to secure the result for the Red Devils.
A 3-1 win was possible thanks to two Casemiro goals and a Fred strike.
"What a player," wrote the Argentine, alongside a clapping emoji on his Instagram account, showcasing a picture of Mainoo.
The youngster has managed two goals and two assists in 11 Premier League 2 matches this term.
While Garnacho is the higher rated of the two, Mainoo has quietly become an option for coach Erik ten Hag in matches this season.
