Arsenal has failed to win a Premier League title since moving to the Emirates Stadium in 2006.
Kolo Toure believes the cost of building a new stadium is the reason Arsenal has failed to win a Premier League title in over a decade.
The London-based club played at Highbury before electing to build a new 60,000-capacity venue, which it moved to in 2006.
Arsenal's last league title came in 2003-04, when the club went unbeaten for the whole season — and it has only won four trophies since.
Toure heaped praise on manager Arsene Wenger for his efforts since then, with the club having to drastically reduce costs.
