The fact that Arsenal need a commanding midfielder is old news and has been talked about for various seasons.

Arsenal remain keen on FC Porto midfielder Danilo
It has been reported that Arsene Wenger is certainly looking to bolster that department and is interested in signing Porto's Danilo Pereira. Apparently, some scouts were assigned to see the midfielder in action in their recent game against Sporting.

Sporting's William Carvalho has also been on the Arsenal radar for various seasons but it has been reported that Arsenal are more keen to sign the 24 year old Danilo.

One of the major reasons for Wenger to bolster his midfield department is due to the imminent departure of his veteran midfielders which includes the likes of Rosicky, Flamini and Arteta. They are currently out of contract of next season and will most probably leave the club at the end of the season.

Arsene Wenger was criticized for not improving his midfield department and it was cited as one of the major reasons why they lost the title to Leicester City this season.
