Emery revealed why he substituted Lacazette

Arsenal striker Alexandre Lacazette was raging after being substituted during their win at Burnley.

After setting up Pierre Emerick Aubameyang for his second goal against the Clarets, the French star took out his frustrations on the sideline as he made way for Alex Iwobi.

Lacazette could be seen passionately gesticulating to coaching staff and took his time taking his seat.

However, Unai Emery's decision was proved a wise one with Iwobi scoring in the 91st minute to make it 3-1.

Emery on Laca:

'I think he is happy with our victory. Only he wanted to score and when a striker doesn’t score, I like that he can be angry with his situation. But he worked very well today. The last matches are the best he has played. He is coming back as the best Lacazette.' pic.twitter.com/E4ZTsGUXxW
