Las Palmas have completed the signing of former Hammer Jonathan Calleri on loan after he completed a medical at the Spanish La Liga club based in the Canary Islands.

The 23-year-old Calleri spent last season on loan at West Ham but scored only once in 17 appearances.The Hammers reportedly paid a £4m loan fee for his services last season.

Controversy has followed his ownership in the past few years. While still at Boca Juniors, Calleri was bought by a mysterious group of agents for who had him signed for Uruguayan side Maldonado.

Calleri never made a single appearance for Maldonado, who play their matches in front of crowds of less than 300 in a ramshackle stadium located in Uruguay’s seventh most populated city. Since 2009, when the club was sold to unidentified foreign investors, they have spent almost £28m on players but never quite managed to win promotion in a division where average salaries are around £300 a month.
