When we walked past the ticket office at 11-15 the queue was massive and they all seemed to be West ham fans so had a 100 city fans you would have to get there 2 hours before kick offI got the same email.
The perimeter search last season was the first time that had happened to us at West Ham. As for collecting tickets, I thought the club said this wouldn't be a collect on the day fixture when tickets were sold. So either this is for duplicate tickets or someone at City doesn't know what they are doing. Or both.
