Middlesbrough are in advanced talks to sign former Arsenal striker Yaya Sanogo, Football Insider can reveal.

Neil Warnock’s side are working on recruiting the Frenchman, 27, as they look to bolster their attacking ranks ahead of the new season.

A Boro source has told Football Insider that discussions are progressing well and the club are hopeful of signing Sanogo on a free transfer.

He is without a club after his contract at Ligue 1 outfit Toulouse came to an end earlier this summer.

Sanogo spent three years at the south of France side following his transfer from Arsenal in the summer of 2017 on what was also a free.

He was not a regular member of the Toulouse starting line-up last season, starting just nine of their 28 league matches before the season ended prematurely.

In 72 matches, Sanogo scored 16 times for the club as he struggled to recapture the prolific form that persuaded Arsenal to prise him from Auxerre in 2013 when he was just 20.

Former Gunners boss Arsene Wenger hailed his countryman as a huge talent but he struggled to live up to that billing in England.

The 6ft 4in striker scored just once in 20 Arsenal matches although he fared slightly better while on loan at Crystal Palace and Charlton Athletic.

Sanogo has never scored in the Premier League but his eight matches in the Championship have yielded three goals and that is considered more indicative of his talents by Warnock.
