“I’m watching games and maybe he needs to be a bit more aggressive,” Sagna added.
“Be a leader, especially in his position. I don’t know if he speaks English. This could be a problem when you come to a new country, but you need to adapt fast, you don’t have time.
“Time is a luxury you don’t have when you come to a club like Arsenal because you have to play straight away.
“To adapt it takes months and Mikel probably saw a problem and thought ‘you need to be more aggressive, you need go out somewhere and play’.
“Then when he comes back, he will have the mentality needed for the Premier League.”
