Arsenal set to announce BIG TRANSFER

Arsenal are understood to have reached an agreement over the sale of Costa Rican winger Joel Campbell to Palermo, according to reports.

The talented winger failed to impress in his short spell at the Gunners, and was shipped out on loan to Villareal for the second half of last season.

Campbell is believed to be desperate for regular first-team action, and The Metro claims that the Gunners have finalized a £7.1m for his transfer to Italian side Palermo.

The 23-year-old made just four appearances for the Gunners since his arrival in 2011.
