Manchester United's young players were delighted for former teammate Teden Mengi on Saturday.
The centre-half impressed as Luton won at Everton to record a first ever victory in the Premier League.
Mengi joined Luton in the final week of the summer market and has quickly settled at Kenilworth Road.
United midfielder Hannibal Mejbri posted his congratulations to Mengi in the aftermath, stating: 'en PATRON' which translates to 'as a boss'.
The likes of Shola Shoretire, Ethan Laird and Zidane Iqbal also sent their best wishes to the defender.
