Replying to another former Hammer in Richard Garcia, the Manchester United midfielder reflected on his days in a young West Ham side - suggesting they were some of the best in his career.
The 34-year-old spent five years at Upton Park, although that included two loan spells elsewhere.
He then joined Tottenham Hotspur before leaving Spurs for Manchester United, where he has played his football from 2006 to the present day, winning multiple titles during his time at Old Trafford.
The experienced midfielder is currently one of three main central playmakers who are rotated by Louis van Gaal at Manchester United, alongside Bastian Schweinsteiger and Morgan Schneiderlin.
For England, meanwhile, the 34-year-old could be one of Roy Hodgson's starters at Euro 2016.
Carrick clearly has fond memories of his West Ham days, however, as do many of England's best players in the last few years - Frank Lampard, Rio Ferdinand and more.
As for the Hammers these days, a tough trip to Crystal Palace awaits Slaven Bilic's men this weekend.
