Our future was/is(?) Walcott and he's on the bench now for an unknown reason for me. People saying he doesn't help in the defense, not as much as Welbeck but he's not another Podolski example in that sense. Walcott's importance on the wing is too important to hold on the bench. Can't complain when he scores goals, setting up for goals and be a threat behind the defense continuously. His decisions going forward is one of the best we have in the team, there's no doubts and his partnership with Giroud was so so good. Also him and Özil have incredible stats when playing together. So if Danny contributes a lot to the defense, he doesn't contribute that much forward because his end product isn't even half of Theo's. It's like watching another Oxlade-Chamberlain with more physical attributes.
Bellerin is for me our future right-back. Debuchy will play for another 2 or 3 seasons for us and then be sold as his contract goes out in 2019. Hector is hopefully ready to play regularly season after season when he's 23 years old. He's grown a lot since Debuchy's injury.
The Ox? For me a wing player but Arsene is seeing his future as a central midfielder. Will he make it? Well we have Özil, Wilshere, Ramsey, Coquelin who will hopefully play centrally for many years to come. Santi and Rosicky won't be in the team in 3 years I guess. Crowley will most likely break into the first-team in the upcoming 3 years. Zelalem is another very bright prospect, born 1997 and 18 this year as Crowley. Time to think about them? Arsene is seeing Chambers' future as a central midfielder but as a defensive/sitting one. On that position we also have Bielik who is very very young and surely won't be in the first-team regularly (on the bench/starting) for another 3 years, as we probably are going to buy a DM in the summer anyways but also depending on Coquelin's form. However I think we should buy a DM to make the competition bigger when Arteta's body isn't physically good and Flamini likely to be released this summer. Diaby is finished, that's it.
Akpom? How good can he be? Should Arsene go for him instead of Sanogo who has yet to find form? I think so. From the little I've seen from Akpom I think he looks more capable of being successful to our style we play, also been a gunner for 13 years. He got pace, decent ball controll and willing to go straight forward. His goal scoaring record for U21 is impressive.
Other interesting players: Joel Campbell, Gnabry, Toral and Wellington Silva.
