Arsenal: Mikel Arteta hails 'decisive' summer signing after stellar debut

The left winger has played for the Gunners in pre-season but made his competitive debut in Sunday’s Community Shield.“He’s come into the team and really organically he’s fitted in,” Arteta said of Tzolis afterwards.“He’s a really intelligent boy, and he has a massive quality, which is that in the last 30 metres, he is so composed to pick people out in and around the box or to finish.Bright start: Christos TzolisGetty“He has shown that two or three times, and he was decisive.”The Arsenal manager was asked whether his quality in the final 30 minutes is coachable and whether he can get even better.“That is a natural quality,” Arteta replied. “With more quality around him, the numbers will be higher. It is not a coincidence.“He is a really consistent player in everything he does and, yes, I’m really impressed with him.”
