I can't help but think that Lallana signed his last contract with us (and many of us were surprised when he did) with some assurances from Les Reed that Reed then went back on, such as being allowed to move if a big club came in. Adam did say it got heated but also said he never refused to play and regretted how it happened.

I wouldn't want to see him back on a Walcott deal, but at the right price.......
