West Brom's players were left frustrated by defeat to West Ham United on Tuesday.
Matheus Pereira thought he had earned the relegation-threatened Baggies a point when he cancelled out Jarrod Bowen's opener but Michail Antonio, currently West Ham's only recognised striker, scored the winner.
Albion defender Kyle Bartley told the club website: "There's a sense of disappointment because we feel like we deserved to get the draw, but at this level any mistakes are costly.
"After the Wolves game we were confident of getting a result. We're disappointed not to, but the effort was there and I think it was a good performance."
