Arsenal are planning to expand their Emirates Stadium to boost matchday revenue, with speculation ongoing for several months.
According to former Everton CEO Keith Wyness, Arsenal are considering adding a third tier, similar to Barcelona's Nou Camp.
The Telegraph reported that Mikel Arteta's side are planning a major expansion, potentially forcing them to play home matches at Wembley.
