Trent Alexander-Arnold was brutally dropped from the starting lineup for Real Madrid's victory away to Real Oviedo on Sunday.
Alexander-Arnold joined Real from Liverpool in the summer and featured for the Spanish side at the Club World Cup.
However, he endured a difficult LaLiga debut with an unconvincing performance in the win at home to Osasuna.
Dani Carvajal started at right-back against Oviedo, with Alexander-Arnold replacing him in the 87th minute.
Alexander-Arnold will hope to be back in the starting lineup when Real host Mallorca next weekend.
Kylian Mbappe scored a brace against Oviedo before Vinicius Jr (who like Alexander-Arnold had been left out of the starting lineup) made it 3-0.
One user suggested that Alexander-Arnold is set to learn a 'brutal' lesson.
They wrote: 'Trent is about to learn a brutal lesson at Real Madrid. But he's a big boy he'll be fine.'
Another user wrote: 'Trent Alexander-Arnold, sitting right back on the bench for Real Madrid'.
Furthermore, another user stated: 'Trent Alexander-Arnold, I'm afraid you may be holding bench for a while. My captain is back. Solid display from Carvajal.'
In addition, another added: 'Trent Alexander-Arnold went to RMA to sit on the bench?'.
