Sam Allardyce admits he made the decision to quit West Brom because he sees himself as a short-term manager.
The boss had held talks with the Baggies following their relegation from the Premier League and will leave after Sunday’s finale at Leeds.
Allardyce replaced Slaven Bilic in December but had a break clause in his contract which could be activated if Albion, who are second bottom, went down.
“Ultimately, we were unable to accumulate the points total required to keep us here, but Sam certainly restored pride with a number of resilient displays.
“Sam, Ken (Chief Executive, Xu Ke) and I have discussed at length our plans for the future and we very much hoped to have Sam in charge for next season and beyond.
“Sam and his coaching staff have been excellent to work with and I would like to thank them all for their efforts.
“Sam has given his reasons for leaving and we respect his decision. He has been brilliant to work with and I wish him, Sammy and Robbie all the very best in the future. They will always be welcome at The Hawthorns.”
