Liverpool's £35M striker has become West Ham's £15M man as Carroll seals his move down south.
Andy Carroll joined the reds in January 2011, in a frantic deadline day that saw Fernando Torres move to Chelsea for £50M.
Carroll struggled under the weight of his transfer fee at times, and battled to overcome an injury that he had suffered before joining the reds.
Kenny Dalglish was a constant defender of the players interest, and towards the end of the 2011/12 season did appear to be heading in the right direction.
However, the arrival of Brendan Rodgers effectively ended Andy's Liverpool career - and he was loaned out to West Ham for the season.
West Ham and Liverpool reached agreement on a fee of £15M in May, but Andy took his time before completing the move to the London club.
Carroll said:
"It's fantastic for me to be here. I really enjoyed last season, and that shows in me coming back and making it permanent.
"The fans, the lads and the club itself have been great to me, and what I wanted to do was come back here and play football.
"Since the end of the season I've had a lot of time to think, I've missed it and that's why I'm back.
"Getting promoted the season before last, then finishing where we did - we did great, and it can only get better for us.
"The way the club's being run, obviously getting the new stadium and everything like that, it's only going up."
Anfield Online would like to wish Andy the very best in his future career.
