Oxlade-Chamberlain hails the influence of Arsenal's star striker Alexis Sanchez
Alexis Sanchez's dynamic performances are inspiring the other Arsenal players to raise their own game, according to midfielder Alex Oxlade-Chamberlain.
Chile forward Sanchez was again the Gunners' talisman against Stoke on Sunday, scoring twice and setting up the opener in the 3-0 victory which moved Arsene Wenger's side to within a point of fourth-placed Manchester United.
The work-rate of the South American has been impressive since completing a £32million summer move from Barcelona, and England international Oxlade-Chamberlain revealed the rest of the squad are determined not to let their own high standards slip.
"When you see someone working hard from the front and maybe if they close three players down and don't win the ball back, then you are not there to back him up, you do have to look at yourself and think 'why was I not there to help my team-mate out?' It does set the tone for the rest of the team," said Oxlade-Chamberlain.
"If the boys up front react quickly when we lose the ball, it brings the midfield with them, full-backs and the defenders to switch from attack to defence. It is something that we work hard on.
"Alexis does it better than anyone I have seen. He has come from Barcelona, and it is a strong philosophy that they play by, so maybe he has picked that up there and brought that to us.
"There are definitely a lot of boys learning from him. We know we have got the quality going forward to cause teams damage, so it is always important to make sure we match teams physically."
