It was a historic day for West Ham United as they began their Premier League life at their new stadium.
After 112 years playing at the Boleyn Ground the Hammers moved into the London Stadium - known to everyone in the whole world as the Olympic Stadium - this summer.
And today they played their first league match at the ground, making it the 55th stadium to host Premier League football in England.
But it appears the stadium itself is not quite finished.
One fan tweeted a picture of his position in the stand which showed bare concrete, apparently where the seats should have been.

Meanwhile, some of those who actually *do* have seats might still have a job seeing the action given how far some are from the pitch.
Needless to say, the internet had something to say about that.
