He always has a get out clause in his tweets.
"As I'm being told a big player is being targeted, we're working on it" This is a standard type of tweet from him.
If nothing comes off, he says he was simply told, and all he's doing is passing on a message, simultaneously shifting the blame.
Then if it happens, he's certified itk?! I'm sure he has some connection within the club but it's not like he's got his feet under the table with Gazidis and Wenger either side of him.
