Carragher wrote in the Daily Mail: "Andy, no doubt, will believe he has a point to prove given how quickly Brendan Rodgers ended his time at Anfield - he only got two brief substitute appearances that amounted to 18 minutes - but the decision to move him on was in everyone's best interests.
"Now, I want to make it clear I've no axe to grind with Andy. I found him to be a good lad and his spell at the club wasn't without highlights. He did what every Liverpool No 9 should do and scored two winning goals against Everton, including one at Wembley in the 2012 FA Cup semi-final.
"I wanted Liverpool to sign him, especially after he tormented our defence one day at St James' Park. If we could have got him for between £12-15m, it would have been good business. The feeling around the club when we were in for him was that maybe he could mature into our Didier Drogba.
"Unfortunately, though, Liverpool's decision to pay £35million was a big mistake and it never did Andy any favours. He started well, with two goals against Manchester City on his first start, but it quickly became apparent he wasn't the right fit for the club."
