The Arsenal Supporters' Trust has urged the Premier League club to overhaul their player recruitment structure after a summer that saw the Gunners fail in their pursuits of Gonzalo Higuain, Luis Suarez, Wayne Rooney and Luis Gustavo, reports BBC Sport.
Despite the arrival of midfielder Mesut Ozil for a club-record £42.5m, the AST, whose members hold around 4.5 per cent equity in the club, issues a statement which says: "We welcome the statement of intent Arsenal have made with the signing of a world-class player like Mesut Ozil.
"It is a transformational signing for the club in terms of both transfer fee and wages paid. It is, however, frustrating that once again a window has closed with over £50m left unspent. The AST would like to see all available resources put toward strengthening the team."
