Tight dressing-room squeeze for Spurs
The size of the visitors' dressing room at Old Trafford has been almost halved as a result of changes made in an effort to ensure there is no repeat of the tunnel brawl that erupted in December between rival players in the match against Manchester City.
The new entrance to the away team's dressing room takes them from the main tunnel directly into their room. Previously, the away dressing room was entered via the second door in the small corridor off the main tunnel. It was from that door that Cesc Fabregas launched a slice of pizza at Alex Ferguson in the infamous 2004 'battle of the buffet'.
United have also modernised the home dressing room, giving them a new lay-out where the players sit around three sides of the room on individual seats with their locker space built in behind them.
At Spurs' new stadium, there will be a generously-sized away dressing room as well as specialist bigger versions to accommodate the NFL teams that will play there every year.
Stadiums must now provide separate dressing rooms for players younger than 18, who are not permitted to change with adults under safeguarding regulations.
The smallest away dressing room in the Premier League is widely recognised as being at Selhurst Park.
