In his column for the Telegraph, Hansen wrote: "Torres worked hard against Manchester United, but there is no escaping that he had an absolute stinker before he was taken off with 13 minutes to play.
"He was brushed off too often in challenges with Jonny Evans and Rio Ferdinand and it is obvious that he is playing with very little confidence.
"Compared to the standards he has set as a Liverpool player, Torres has been poor this season, and there are now a lot of supporters who would be happy to see the club bite the hand off anyone prepared to offer £40-50 million for him.
"I don’t know what Kenny plans to do with Torres, but he defended his performance after the game, gave him the thumbs up and cajoled him when taking him off. That indicates that he is ready to encourage him and try to get the best out of him.
