This is not an isolated case though. I'm certain Liverpool fans really believed that Luis Suarez was signing on for life when he committed to a new deal at Anfield. And with good reason. Where is he less than 12 months later?
The game is littered with other examples. Who would've thought that Christiano Ronaldo would've ended up at Real Madrid 12 months after committing his future to Manchester United?
What about Gareth Bale? He signed a multi-million pound deal at Spurs didn't he -12 months before his world record move to Madrid? What a co-incidence!
Aguero signed a new deal with Atletico Madrid 1 year before joining Man City, as did Costa before joining Chelsea. Lallana signed 1 year before joining Liverpool. Andy Carroll signed a 5 year deal with Newcastle and joined Liverpool 3 months later! When Anelka joined Chelsea he’d only signed a new contract 6 months previous. Slightly different but Falcao and James Rodriguez were only at Monaco for a year before joining Man Utd and Real.
