Alexis Sanchez's arrival has left the Arsenal squad "buzzing" ahead of the new campaign, according to defender Carl Jenkinson - with more new signings expected before the Community Shield against Manchester City at Wembley.
Arsenal moved swiftly to close out the transfer of Chile forward Sanchez in what is said to be a £30 million deal from Barcelona. Jenkinson believes he can help the FA Cup winners target more success: "He is world class and they are the sort of players you want to see at the club.
"The squad are buzzing as much as the fans, because if you are going to push on as a club and really compete for things, you need to sign top players," Jenkinson said on www.Arsenal.com.
