Gibbs: Brom not good enough
Kieran Gibbs claimed West Brom were simply "not good enough" this season and apologised to the club's fans after relegation was confirmed.
The Baggies' eight-year spell in the Premier League came to an end after Southampton beat Swansea 1-0 at the Liberty Stadium on Tuesday night.
They needed a draw to keep their hopes alive of staying in the top flight for another season, but even that would have been a tall order on the last day of the campaign.
Defender Gibbs tweeted on Tuesday evening: "Horrible feeling to be relegated, especially after our recent form as a team! It's been a wild season on and off the pitch and has been a huge learning curve. Whatever has gone on this season there are no excuses we haven't been good enough for the majority of it.
"For that we are sorry to the W.B.A fans who have been quite unbelievable considering the circumstances. Thank you for your amazing support this season!"
Relegation came on the same day interim boss Darren Moore was named Premier League Manager of the Month for April.
After picking up just four points from a possible 30, Tony Pulis was sacked two days after losing 4-0 at home to Chelsea and was replaced by Gary Megson, who took temporary charge. Alan Pardew was named permanent manager but was sacked on April 2.
