Dani Ceballos wasted no time making an impact on his home debut.
The Spain Under-21 international set up Alex Lacazette and Pierre-Emerick Aubameyang on his first showing at Emirates Stadium, producing a man-of-the-match display to help us beat Burnley last weekend.
But his performance came as no surprise to good friend Hector Bellerin.
"I think Dani's one of the best players I've seen in my career," the defender said. "I've played with him since we were like 18 or 19 years old. We've played in the under-21s, we get on really well off the pitch.
"He's a great player, I think he's going to be a great addition to the team and the Premier League is going to be very different to any other league, but he's shown in training that he's ready for it.
