It was all going so well for Chelsea.
Antonio Conte has been able to do no wrong this season. Eden Hazard is back to his best.
And despite the defeat to Crystal Palace, the Blues should still be on course to win the Premier League for the second time in three years.
However, if there’s one thing that can scupper a team’s progress, it’s a move to a new stadium. Just ask West Ham.
The east Londoners’ woes in Stratford are well-documented enough.
That doesn’t seem to have deterred Chelsea from attempting to ground share with them, though, as the two clubs have begun talks.
The Times are reporting that while Chelsea are hoping to play at Wembley when Stamford Bridge is being redeveloped, they are not 100% sure they can convince the FA.
It’s led them to consider alternatives, and the London Stadium is the only viable option.
Arsenal’s Emirates stadium has a limit on the number of events it can stage, and the Rugby Football Union has opposed them playing at Twickenham, as have local residents.
A season spent at West Ham would no doubt cause controversy among the supporters, but the club may have nowhere else to go.
