I wouldn't be so sure of that. But whether we would accept him back is another thing.
Torres is 28, FSG policy states that 27/28 is the cut off as the re-sale is not at it's best why do you think we sold him at such a great price? There is no way Fernando Torres is worth 50 million right now and I believe you could contact Chelsea and buy him for around 15m max at the end of this season or January IF he fails to perform.
It seems Fernando is struggling mentally and physically the thing that made Fernando so great was his pace and after so many injuries to his knee and Liverpool playing him when he wasn't 100% didn't help but we needed him and he still performed to the best of his ability.
Fernando has hit 1 goal in 23 games for Chelsea which is an absolute shocking goal firing rate for a player who fired in goals for Liverpool.

Above is his record for Liverpool and as you can see he was played less and less towards the end of his career due to his injuries and he had no rest even at International level as Spain played in the following:
2006 world cup qualification
2006 world cup
2008 Euro's
2009 Confederations cup
2010 Euro 2012
He hasn't had a long rest in years and his body isn't able to cope with the physical pressure of the Premiership and I swear he said he couldn't keep up at the top level due to the physical level of our league and said players like John Terry and Steven Gerrard have great bodies to be able to cope with this. I'm 99% sure this was torres but couldn't find the media link for this he said this the year before he moved.
