Martinelli wants to be important at Arsenal as soon as possible and does not understand why he has only played four games so far this season. The Brazilian, according to the 'Mirror', is unhappy with Mikel Arteta.
The manager himself came out to give him some advice and asked him to be patient because his time will come sooner or later: "He needs time, he is so willing and so anxious that he can block his development".
"Sometimes he doesn't understand my decisions, but the only reason I make them is to help him. He has to improve when he doesn't play. You have to know how to suffer when you are on the bench," said the Arsenal boss.
For Arteta, players have to be able to swallow "ego and anger" and "all the will to play a game".
