The 21-year-old striker is reportedly unsettled at the Serie A side having fallen out with manager Simeone Inzaghi and club captain Lucas Biglia. It is now being reported by Transfermarketweb.com, among other sources, that the Senegal international is less and less likely to agree a contract extension with Lazio, with his current deal set to expire in June 2018.
Arsenal and Chelsea are said to be scouting the young forward, with reports yesterday suggesting Lazio would allow the player to leave if a £26million offer comes in this summer.
Keita, who has made 17 Serie A appearances and scored six goals so far this season, is also still being tracked by AC Milan as well.
Keita looks a promising talent, but it remains to be seen whether Arsenal make a move for him this summer, with the Gunners already well equipped upfront.
