Alex Oxlade-Chamberlain admits it's exciting playing with Arsenal attacking duo Mesut Ozil and Alexis Sanchez.

Sanchez hit a hat-trick in Arsenal's 5-1 Premier League victory at London Stadium, with the Chile star also turning provider for Ozil to hand the Gunners a first-half lead.

"It felt like that, especially [in the] second half," Oxlade-Chamberlain told Arsenal Player. "It seemed like we were flowing.

"The game opened up a bit and when we were going forward we looked like we were all in sync.

"Alexis was making runs, Mesut was making runs and the boys were coming in behind them.

"We felt like we knew what we were doing and we were creating opportunities.

"Once you start getting one goal or opportunities open up, your hunger for it grows even more and I think I've seen that over the years in Alexis.

"He scores two and he's unhappy he hasn't scored a hat-trick."
