He was presumably happy to sign for BHA once he realised the silly money he thought he was worth was not available at Saints,or given his hip problems,the Saints cooled their interest.
As for "statement of intent", its a pretty sorry one,if you have to take back a player who obviously did not really rank your club as his first choice.
Nothing against BHA,you've got a decent manager in Poyet,and hope you do well,but this episode appears a bit of an embarrasment for you frankly.
