Martinelli juu ya Arteta:
"Nilipokuwa majeruhi, alikuwa akinipigia simu na kuniuliza hali yangu jinsi nilivyo. Ni meneja mzuri sana, lakini si hivyo tu, mtu mzuri sana."
Speaking to
The Athletic, he said: "I always try to be positive, but it was a really tough time. My parents are always with me, saying good things, saying I need to believe in myself and let any bad things pass.
"Then the next day you work hard and five and a half months after I suffered the injury, I was back playing. I did my rehabilitation in England and had a bit of recovery time in Brazil.
"It was frustrating not to be able to help my team-mates. But those bad times have passed now.
"Mikel is a really nice guy and a lovely person. As a manager, he is unbelievable. He always tries to help everyone.
"When I was injured, he was calling me and asking how I am. He is a very good manager, but not only that, a very good person.”
