Arsenal midfielder Mikel Arteta has welcomed the arrival of Alexis Sanchez.
The Chilean completed his move from Barcelona yesterday.
"I'm very positive about next season. What the club has done today, signing Alexis Sanchez, is great," said Arteta.
"I know Alexis very well because I am a Barcelona fan and he has been tremendous in the last 12 months.
"I spoke to him this morning. He said is very excited and wants to get involved as soon as possible and hopefully he can deliver.
"He is a player who is going to give us a boost and increase the scoring capacity of the team.
"I think we have been missing that pace in behind. Sometimes we played with Cazorla, Giroud, Wilshere up front - and we had no pace."
