Arsene Wenger has offered an explanation as to why he keeps substituting Alexandre Lacazette.
Since the Frenchman joined Arsenal as their club-record signing in the summer, Lacazette has completed the full 90 minutes just once.
He started and finished the opening game against Leicester, where his goal helped the Gunners to victory.
But the 26-year-old has been substituted in ten of the subsequent 12 games, coming on in the second half of the other two.
“First of all, I would like to say in my job, you sub strikers more than defenders,” he began on Tuesday. “They have to create, provoke and be incisive.
“He has adapted physically to the Premier League and I am very happy with his work.
“I have other options on the bench who are fresh and give us other variations in our attack.
“Physically, the Premier League demands a huge intensity of work.
“A lot of teams change their strikers around 60-80 minutes. They work on their own up front against two or three people.
“It is much more exhausting physically and mentally.”
