West Ham have been linked with moves for Arsenal defender Johan Djourou and fellow centre-half Abdoulaye Ba.

It has been claimed the Switzerland international may leave the Gunners this summer after failing to hold down a regular place in Arsene Wenger’s side.

However, Djourou is under contract until 2015 and it is therefore likely to take a significant fee to secure a move for the 25-year-old.

Meanwhile, Hammers scouts are said to have watched 21-year-old Senegal centre-half Ba, who is on loan with Academica from fellow Portugese side Porto.
