Despite losing Alexis Sanchez, Olivier Giroud and Theo Walcott to Premier League opposition, Arsenal ended up having a very successful January transfer window.

Arsene Wenger secured a swap deal for Henrikh Mkhitaryan from Manchester United and splashed a club-record £56 million to sign Pierre-Emerick Aubameyang from Borussia Dortmund.

Arsenal's manager now has two world-class strikers and attacking midfielders at his disposal, which has raised questions of how exactly he plans to play them all.

We recently discussed the three ways Arsenal could line-up with Aubameyang and Lacazette in the same XI, and today, ahead of the weekend's fixtures, Wenger gave his thoughts.

Asked if the 'big four' can play together, the Frenchman responded: "It's always possible. Will I do it? Maybe. I don't know, but I think it's possible."

Aubameyang is widely regarded as one of the best strikers in the world right now, which is exactly why Wenger spent a club-record fee to sign him.

"He's a typical striker, great pace, good ration with game splayed and goals scored," he added. "A good work rate, a team player.

"We lost some goals, Sanchez, Giroud and Walcott - he will compensate on that front."

Wenger is clearly open to the idea of playing Aubameyang and Lacazette up front together, but you could hardly blame Lacazette if he feels worried about his place at Arsenal.

The France international, who has nine Premier League goals in 25 games, has struggled in his debut season for the Gunners and is currently lacking confidence.

However, he's not about to receive a confidence boost from Wenger, who gave a pretty savage response when asked whether he's reassured Lacazette following Aubameyang's arrival:

"I don't reassure anybody. It is a competitive sport and you must fight for your places. You have to show them respect and they have to accept it is a competitive world."

Who knew Wenger could be so ruthless? Rather than give assurances to Lacazette about his place in Arsenal's starting XI, he wants the 26-year-old to fight for his place - and rightly so.

Starting games should never be guaranteed at a big club like Arsenal, so Lacazette needs to pull his socks up and show why he's worthy of playing alongside Aubameyang.
