Former Arsenal striker Kevin Campbell has openly told manager Unai Emery to sign Napoli centre-back Kalidou Koulibaly.

The Senegalese defender has been linked with the Emirates move during the summer transfer window but the Gunners failed to meet a £53m price-tag.

The North London club have eventually opted to bring in ageing defender Stephan Lichtsteiner and Sokratis Papastathopoulos.

However, Arsenal legend Campbell took to social media to call on Gunners manager Unai Emery to make a move for the 27-year-old Senegal international.

Replying to a tweet from former Liverpool ace Don Hutchison, Campbell posted: “Arsenal should get sign (sic) him 100% ASAP.”

Koulibaly played Napoli’s final Champions League group stage game as the Italian outfit were knocked out by Liverpool on Tuesday night.

Koulibaly was praised by many for his performance against Liverpool last night but Manchester United legend Rio Ferdinand was not impressed.

“You know he’s strong, you can’t get tight to somebody who’s stronger than you like that,” Ferdinand said.

“If you get tight, he feels you and uses you and rolls you, which he did to the full-back there.”

“And Koulibaly, he stood him up, when past him one v one.”

“That’s the first real question we’ve got to ask about Koulibaly, the centre-half.”

“He came with a big reputation coming into this game and he got disposed of here.”

“One v one, stood up, goodnight, and the goalkeeper here gambled. He dived out the goal and dived out the way really.”

The Gunners have conceded 20 Premier League goals this season despite being on a 21-match unbeaten run in all competitions.

Arsenal are back in action on Thursday night as they take on Qarabag in the final Europa League group game at the Emirates.
