The move to Nottingham Forest came about quickly, and was rushed through just in time for the 5pm deadline on Friday, but Adam reveals he had no hesitation in agreeing to it - despite his affection for the Hammers.
"I enjoyed my time at West Ham; it is a great club with some nice people and it was a good experience but this opportunity has come along and Alan Pardew has obviously accepted the bid.
"Forest is a fantastic club just like West Ham is, and they both belong in the Premier League, so I am looking forward to the challenge."
Adam agrees with Alan Pardew's assertion that he has gained as a player in his nine-month stay at Upton Park, and adds:
"I have played with some good players and of course Michael Carrick was the same position as me - I have definitely improved as a player.
"The fans were great to me as well and it is just a shame I couldn't have played more in front of them."
And so Adam's swansong proved to be at Stamford Bridge last week, before being substituted by Mark Noble.
"I started against Chelsea, probably due to the fact that Carl Fletcher was cup-tied, and I enjoyed the game, but that is football - one minute you are at a club and the next minute you are signing on the dotted line for another one," he says.
"But it is good that it has been done quickly and I can get back to playing again."
Although he has swapped a promotion chase with a relegation battle, he says:
"It is not a problem at all with the players they have got - there is some fantastic talent and a lot of good young players as well."
