West Ham United lost against Everton in the Premier League on Sunday.
Danny Gabbidon has criticised West Ham United manager Slaven Bilic on social networking site Twitter.
The former West Ham defender was not impressed with a substitution that Bilic made against Everton on Sunday afternoon.
Bilic took off midfielder Pedro Obiang and brought on winger Andre Ayew in the 60th minute of the Premier League encounter at Goodison Park.
The Hammers were 1-0 down at the stage, and conceded the second goal on 76 minutes to suffer a 2-0 defeat.
Over the course of the 90 minutes at Goodison Park on Sunday afternoon, visitors West Ham had 51% of the possession, took 13 shots of which just three were on target, and earned eight corners, according to BBC Sport.
The Hammers are 16th in the league table at the moment with just 10 points from as many matches.
The London outfit are only three points above the relegation zone and are still not out of danger yet.
West Ham will return to action next weekend when they take on Stoke City at the London Stadium in the Premier League.
