A Jarrod Bowen brace gave the Hammers a two goal advantage going into halftime before a Jack Grealish strike and a Vladimir Coufal own goal saw the visitors equalise.
However, the Citizens blew a golden opportunity to complete the comeback and extend their lead at the top of the Premier League to six points as Riyad Mahrez missed a late penalty.
For West Ham, a top-six finish is still very much possible, however, the day was about Mark Noble who played in front of his home fans for the final time after an 18-year-long career with the east London outfit.
Although a victory would have been the icing on the cake, a poor defensive performance from left-back Aaron Cresswell contributed to the Irons’ collapse.
The Englishman recorded just 32 touches all match, fewer than the 48 of goalkeeper Lukasz Fabianski.
Moreover, Cresswell managed to complete just 12 passes out of an attempted 17 at a 71% accuracy whilst providing zero key passes or crosses and just one successful long ball.
With the 32-year-old busy dealing with the attacking threat of City, the left-back made an impressive seven clearances. However, he only managed to make one interception, tackle and block respectively.
Furthermore, with just two duels won out of an attempted seven, Cresswell ended the match having lost 71.4%.
The 32-year-old has been a loyal servant for West Ham since joining from Ipswich Town in 2014 and, without Noble departing, is one of the Hammers’ longest-serving players.
Moreover, with 40 appearances in claret and blue this term, the defender has been a kingpin.
Therefore, this afternoon’s performance was particularly disappointing given his usual reliability as well as the fact that the Hammers were in an excellent position to secure a famous victory.
Manager David Moyes will certainly have a decision to make over the Englishman’s future though with his contract set to expire next summer.
At 32, the Scotsman may be tempted to look elsewhere for a new first-choice left-back, or at least one that will provide Cresswell with more competition next season, especially if the Hammers are to compete in Europe again after being let down today.
