Arsenal boss Mikel Arteta has claimed that Viktor Gyokeres already understands the importance of the #14 jersey at the club and is ready for the challenge. He also backed the new signing to deliver on the pitch, ahead of his unofficial debut.In his press conference ahead of their pre-season clash against Tottenham Hotspur, Arteta was quizzed about Gyokeres' decision to wear Thierry Henry's #14 jersey. He believes that the striker is determined to prove himself on the pitch, and that shows the right mentality. He said (via Football London):"I use the word conviction and that's the first thing that I noticed when I spoke to him. Someone very determined, someone that was already really attached to the club the way he was talking about the club, the history and in this case Thierry [Henry] and what the shirt represented. He straight away felt it, and when you feel it - go for it."When asked if the striker was going to make his debut on Thursday, July 31, against Tottenham, Arteta added:"I understand he's only done today's session and yesterday very little. We're going to assess tonight how he is and if the medical staff are happy as well with his condition to participate in tomorrow's match then it's a possibility. We're going to discuss that tonight. And with the rest, everybody's going to be okay apart from big Gabi who is still out and Riccy it's probably going to be a bit too early for him tomorrow."Viktor Gyokeres is not the first Arsenal player since Thierry Henry to get the iconic number. Theo Walcott, Pierre-Emerick Aubameyang, and Eddie Nketiah have also worn the number at the club.Mikel Arteta heaped praise on Viktor Gyokeres after Arsenal moveMikel Arteta spoke to Arsenal's official website after Viktor Gyokeres' move was made official, claiming that the striker was exactly what they needed up front.
