David Moyes has launched a bid to sign Arsenal striker Joel Campbell.

The Real Sociedad boss tried to sign the Costa Rican last summer but he moved to Villarreal on loan as part of the £11million deal that saw their defender Gabriel Paulista go in the opposite direction.

Real Sociedad boss David Moyes wants to boost his firepower by signing Arsenal striker Joel Campbell

This time Moyes is proposing a £6million bid to take the 22-year-old Campbell on a permanent deal.

Moyes is still clinging to a hope that Danny Ings' move to Liverpool could yet fall through but any deal for Campbell will run parallel to that.

Moyes improved Sociedad's defence last season but was frustrated by their lack of goals and wants to bring in three new attacking players.

Campbell only scored one goal last season but was utilised on the wing and was part of a Villarreal side that was hampered by injuries yet finished sixth.
