Yaya Sanogo is set to undergo a medical at Middlesbrough in the next 24 hours after agreeing terms to a free transfer, Football Insider understands.

This site revealed back in August that the north east outfit were in advanced talks with the 27-year-old after he left Ligue 1 side Toulouse at the end of his contract.

A source at the Riverside has now told Football Insider that the former Arsenal and Crystal Palace hitman is set to undergo the necessary tests before the end of Thursday (10 September) and complete a move back to England.

Sanogo, who joined Arsenal from AJ Auxerre back in 2013, spent four years with the Gunners before he returned to his home country in 2017.

He played just 20 times for the north Londoners and spent time out on loan at Palace, Charlton and Dutch giants Ajax.

While he failed to score in any of his 21 Premier League appearances, he did net three goals during his time in the Championship – all of which came as a hat-trick against Reading.
