Barcelona are expected to announce the signing of Arsenal midfielder Alex Hleb today.

The Sun says Hleb will be unveiled by Barcelona today after completing his £15million switch from Arsenal.

The Catalan giants will pay the Gunners £12.5m up front for Hleb - with the remaining £2.5m based on appearances and trophies.

Bayern Munich, Inter Milan and Real Madrid were also interested in the Belarus midfield man.

But Hleb, 27, agreed a four-year contract with Barca.

The deal is worth around £65,000 a week - almost double his Arsenal salary.

The Gunners signed Hleb from Stuttgart three years ago for £10m.
