West Ham star Cheikhou Kouyate has told the club's official website that youngster Reece Oxford needs to keep listening in order to continue his development.
However, the big story to come from the shock result at the Emirates Stadium was the performance of teenager Reece Oxford.
The 16-year-old, who is a centre back by trade, started in defensive midfield for the Hammers, and produced a superb display to help keep Arsenal at bay throughout.
After something of a dry spell for the West Ham academy, many hope that Oxford can follow in the footsteps of Rio Ferdinand, Frank Lampard, Michael Carrick and Jermain Defoe in becoming a future England international.
There is plenty of excitement surrounding the teenage star right now, and Kouyate told the club's official website that Oxford needs to keep listening and learning in order to fulfil his potential.
"He's someone who listens," said Kouyate. "If I have one piece of advice to give him, it's only to continue to do that, continue to work hard and continue to listen. We must not forget, he is still so young."
It remains to be seen just how much first team football Oxford will be given by manager Slaven Bilic, but his display against Arsenal means fans will expect to see him regularly.
Bilic has to manage expectations and make sure Oxford doesn't burn out from playing so much, but Hammers fans are right to excited about their latest young star, especially considering the recent drought of talent from a once thriving academy.
