Sixteen-year-old West Ham midfielder Reece Oxford impressed on his Premier League debut in largely nullifying the collective threat of Mesut Ozil, Aaron Ramsey and Santi Cazorla, and Hammers boss Slaven Bilic praised his character in responding to the occasion.
"He has a presence, he's mobile and quick, and he can turn and pass the ball, not just square balls," said Bilic, who tasted victory in his first game as a Premier League manager.
"He's not fazed about playing at the Emirates. I tried to help, I told him whatever he did wrong was my fault not his, but I'm lucky he didn't do much wrong.
"He's definitely going to be a big player. Let's be fair, Ozil had his moments but it's not easy to minimalise the game of these world-class players.
"He didn't know until yesterday that he was going to play. We talked the night before but it wasn't like, 'let's sit in a dark room, I have to tell you something Reece, you're going to play'. It was more like chatting.
"That would make pressure. This was natural for him. For today, it was a good decision. He's definitely going to do it [succeed], there's no doubt."
