The agent of Keita Balde Diao has hit out at Lazio over the way they've treated the striker.

On Wednesday, he did not attend training or the celebratory dinner to mark their Italian Super Cup victory.

“He is exasperated over a series of behaviours from the club that he is no longer prepared to put up with," agent Roberto Calenda told La Gazzetta dello Sport.

“Most recently, some insulting graffiti appeared outside the Formello ground, evidently fuelled by the over the top statements that Lazio have made.

“Keita arrived at Lazio when he was a kid. He won over the respect of the football world with his constant effort and quality football. He was only really able to show that in chunks of games and still proved decisive many times, scoring 16 goals last season.

“Now he is 22 years old, the right age for a player to start reaping the rewards of his talent and hard work. Despite the results, Lazio showed they do not believe in him, nor have a project that he deserves.

“After the season with Stefano Pioli, he asked to be sold. The club promised him a place in the side under Simone Inzaghi and a top player's contract. None of this came true. No new contract was proposed in 2015-16 or in 2016-17 and Inzaghi only used him more regularly towards the end of the campaign.

“He is paid considerably less than other strikers who scored fewer goals and played less football in 2017."
