Barcelona are supposedly interested in BR, initially I thought this was negative but upon thinking perhaps not. Clearly he is happy at liverpool and doing extremly well so I don't believe he is seriously considering leaving but I'm sure he can use this as leverage in the future for spending. Anybody seriously think he will leave?
From the way he talks, like he is grateful to the owners that he got time despite having a difficult start + he loves LFC + he is building something + he is quite close to the players, him leaving doesn't seem likely, at least right now. I also think that right now it is at LFC that he has a better chance of showing his value, going to a big club can get him the sack very quickly if he takes time to adjust.
However, a lot depends on the offer he gets from outside and the support he gets within LFC. He did change his partner to a younger better looking one, so he will probably look at options, but can't see this happening in the next 3 years. I think he would like to win a trophy with LFC first, if he feels that this is not going to happen but his credibility has become big, then he might change. Right now, he will feel safer at LFC who can afford to give him better wages which won't be too far from other offers.
