Arteta builds on firm foundations - still business to be done?

Arsenal have one of the best squads in Europe. The Gunners spent £250m last summer, bringing in eight players as they won the Premier League, and have already spent about £200m this year, turning Piero Hincapie's loan deal into a permanent one (£34.5m), signing Bruno Guimaraes from Newcastle United (£75m), Christos Tzolis from Club Brugge (£34m) and Ezri Konsa from Aston Villa (£55m).
