Despite only scoring seven goals, the 6ft 3ins striker proved a popular signing and earned a recall to the England squad for the friendlies against the Republic of Ireland and Brazil.
However, with parent club Liverpool set to be holding out for a £17million, while Newcastle and Monaco also said to be monitoring the situation, the Irons are set for some tough dealings if they are to secure the striker for next season..
Carroll, 24, will also have to consider his own wage demands at any new club, as well as the likely opportunities of regular European football to further push his international career.
Nevertheless, the Gateshead-born forward had nothing but praise for the time spent at the Boleyn Ground.
Speaking on the club's official website, www.whufc.com, Carroll said: "I have enjoyed every minute of being here.
"I have just tried to play my best in every match, score goals and keep myself fit once I got back from the injuries I had and then push on from there.
"The West Ham fans have been brilliant - they were chanting my name all through the match (against Reading), they never stopped and I thank them for the way they have supported me here from the moment I arrived."
Carroll added: "I have worked hard to get myself back in the England squad, trying to play my best for West Ham, so I am really pleased about that. I just have to make sure I keep playing well to stay in there.
"I have had a great season here at West Ham, really enjoyed being part of a great set of lads in the team, with the staff around us and the fans.
"Everyone has been so welcoming to me and I have been over the moon to be here. This is a great club."
Carroll believes West Ham deserve great credit for securing 10th place on their first season back in the top flight.
"As a team, we have made a good transition back up to the Premier League," the England striker said.
"It is a tough thing, but the aim from the start was to try and get in that top 10 and that is what we have done."
Carlton Cole looks set to leave West Ham after saying his goodbye's to the fans on Twitter.
"Life is filled with ups & downs today is a down but i'll be back! Carlton Cole/CFC as i have been called has left the building #UNDERCHUFFED," he said.
"i want to thank the West Ham fans for their support especially the 1's who made the away games feel like a home 1 #COYI
"i came to East London not knowing what to expect but i'm glad i did the last 7 years I've met a lot of good honest decent people #THANKYOU."
