Sadly genuine mate. Have a look on the Brighton Marina Facebook page.
They will show it in the Master Marina and probably even Wetherspoons if you are stuck.
Brighton Marina have just changed their minds and decided they won't be showing any more England games as it will just be tennis. I have it on good authority it kicked off down there Tuesday night which is probably why they have decided against any more.
IF we win tonight gonna land on the Marina Big Screen on Saturday. Will probably have my 5 month old boy with me so hoping it doesn't get too messy down there.
