Chelsea midfielder N'Golo Kante believes Arsenal have done well with the signing of France teammate Alexandre Lacazette.
Saturday's match in Beijing will see Kante face Arsenal's new club record signing, Lacazette.
The striker joined Arsenal from Lyon for £52m earlier this month and Kante admits Chelsea's rivals have made a significant signing.
"I know him from the national team and from what he did in the French league," the midfielder said. "He is a very good player.
"He has scored more than 20 goals every season for the last few seasons in Ligue 1. He is a good player and a good addition for Arsenal.
“He's a goalscorer, clever with the ball and when he has a chance he has a gift for finishing well. He will be a good addition for Arsenal."
