As there are no Arsenal players around thanks to the summer holidays starting, there is nothing wrong with them using the stadium.
While all answers are responses, not all responses are answers.

It's better to burn out, than to fade away.
Hope Messi slips and breaks his leg. Slimey subhuman cunt.
I was thinking caltrops.
Or (and this is even less likely unfortunately) let barca in, let them get their stretch and warm-ups in, release a pack of 100 rabid dingos onto the training grounds and then lock the gate. Hilarity ensues. Sell the video rights to help increase 'other income' and purchase new players. Whether or not we let Cesc train with Barca is up for debate.
I don't see any problem with it. But then again those twats will probably end up using it as an opportunity to tap up Cesc some more.
Don't think Barca need any more opportunities tbh the players have his mobile number.
