Liverpool legend Graeme Souness says people can now see why Manchester United boss Sir Alex Ferguson allowed Carlos Tevez to leave two years ago.

With Manchester City trailing to two goals from Bayern Munich's Mario Gomez, manager Roberto Mancini told Tevez to warm up but was stunned when last year's captain refused.

The altercation with Tevez was clearly seen on television.

"Why didn't Fergie take him? Fergie (Sir Alex Ferguson) is the oldest fox in the business and he must have seen something he didn't like in him," said the Scot.

Mancini is now keen to see the back of Tevez once and for all and Souness believes that is the right move for City, who he thinks could risk losing their manager if they fail to agree.

"He (Mancini) walked into a hornet's nest with him (Tevez) and several other players who were at the club at the time," continued Souness.

"That would cause you to walk away from the job. How can you deal with players acting like that?"
