Alexandre Lacazette has been an instant hit at Arsenal since completing a £52 million move from Lyon in the summer.

Four goals in seven Premier League appearances is a fine return for someone who is still adapting to English football.

The 26-year-old is waiting for his first goal away from home, but there's a sense that when it does eventually come, there will be no stopping him.

One thing Lacazette still hasn't gotten used to is the physicality of the Premier League and how referees seem completely OK with it.

"I have not totally adapted yet, there are things that still surprise me, but I am trying," he told SFR Sport following Sunday's 2-0 win over Brighton & Hove Albion.

"I am watching quite a few matches to understand English football, I am watching quite a lot of my matches with Arsenal and when I look back and see what I didn't do right, I try to learn from it.

"Which hopefully facilitates my progression. The refereeing decisions [still surprise me] and sometimes I think it is a bit dangerous."

Lacazette failed to get on the scoresheet against Brighton but gave Arsenal fans reason to be excited by his and Alexis Sanchez's budding relationship on the pitch.

Not that they should get used to it, though.

Sanchez came close to joining Manchester City in the transfer window and is believed to still want to leave, either in January or next summer.

Should the Chilean move clubs, Arsenal will need to find a world-class replacement - and they might just be in luck.

Lacazette is best friends with Antoine Griezmann no less and said in an interview with Match of the Day magazine today that he wants to bring him to Arsenal.

"Yeah [Griezmann is my best mate], we are very good friends and have lots of fun," said Lacazette, per the Telegraph.

"Our nicknames for each other are Griezzy and Lacaz. If Griezzy visits me in London, I'm going to ask him to sign for Arsenal!"

Imagine if Lacazette somehow managed to pull that off. Doubt continues to surround Griezmann's future and there's no doubt he would be the perfect replacement for Sanchez.

Unfortunately for Arsenal, the France striker is contracted to Atletico Madrid and a top target of Manchester United's, who he has previously expressed admiration for.
