Shiny stadium, no trophies —
Wenger played a pivotal role in the building of Arsenal's new training ground and the move from Highbury to their new state-of-the-art Emirates Stadium, which opened in 2006. However, the funding for the new stadium -- which cost £390 million -- set Wenger back, forcing him to be adopt a conservative approach in the transfer market. So while the team had a shiny new football ground, they were left without any new trophies.
