Debuchy will be Sagna's replacement at right back!

Alexis can play in any of the forward positions in Arsenal's 4-2-3-1, he'd also make an interesting alternative or partner to Giroud. His combination of dribbling and finishing is a bit similar to Aguero and Suarez. One thing Arsenal lacked last season especially with Walcott injured was pace in their game.

I expect Wenger to sign a defensive midfielder and a Keeper before the end of the transfer period.

“I’m looking forward to meeting my
new team-mates and to be playing
for Arsenal in the Premier League
and Champions League. I will give
my best to Arsenal and want to make
all the supporters happy.”

They haven't qualified for CL yet.

Finally!
More please.

Alexis Sanchez welcome to the club of sexy and entertaining football.
This is the Arsenal.
Looking forward to the new season.

"In Alexis Sanchez, Arsenal have signed an attacking midfielder and a forward that has oodles of pace and strength, as well as technical ability and great on and off-the-ball vision. As a physically imposing attacker, Sanchez is built for Premier League success. He comes from a club that has been built on the back of short passing, technical play that cuts open defenses at will. He has a tendency to stretch the defense from the right side by pressing the offside trap and keeping defender on their heels. Combine that with his ability to fend off defenders and hold his own in the final third and you have a ready-made attacker set to light up the Premier. Sanchez has one of the best pairs of shooting boots available for a team in desperate need of someone who can convert chances into goals, one in every three shots hit the back of the net off of his 66 shots last season.

It's likely that Arsene Wenger signed Sanchez to convert him into a strong forward option for when Olivier Giroud is off form, it is much more likely that Sanchez will be utilized in each of the three roles across the front of Arsenal's attack, from the left wing to the right wing to leading the attack out front.

In 141 appearances for Barcelona since his move from Udinese in 2011, Sanchez has scored 47 goals and contributed with 34 assists in all competitions. For his country, Chile, the flanking forward has had roughly the same success rate when firing upon goal, with 24 goals coming in 71 appearances."

Btw he was the fourth top scorer in la liga last season (behind CR7, Messi & Costa) hata with his limited appearances on the pitch. He was also up there with akina Messi in terms of assists....this guy is a beast in front of goal, his qualities can't really be compared with Ozil or Cesc.
