We played there 2 seasons ago and have a reasonable chance of playing there again next month too.
We've actually played there a fair bit, this is our 4th (well 5th but one only had a couple thousand fans) visit in the past decade which is pretty good for a club of our stature.
I don't blame you lot for not selling out as outside of London clubs nobody without huge plastic support would playing there as many times as you have. But it's not correct to allude to Wembley as some mythical venue we hardly ever play at.
Must admit I do hate the semis being at Wembley though. Would much prefer to be going to a different stadium for the game this weekend.
