West Brom boss Tony Pulis said after watching his side lose 3-0 at home to Manchester City that he had picked the wrong team for the game.
The Baggies were second-best throughout after conceding twice in the first 24 minutes, Yaya Toure grabbing both goals.
City captain Vincent Kompany added a third goal in the 59th minute and Pulis admitted he had made a mistake by starting with two forwards - Saido Berahino and Rickie Lambert - rather than playing an extra midfielder.
"I think I've got to hold my hands up," the former Crystal Palace and Stoke City manager said afterwards.
We are after quite a few targets and there will be players that leave the football club as well.Tony Pulis
"I got things wrong. I wanted to play Saido and Rickie, but it went against everything I've ever done against the bigger teams. We've always filled the midfield and been strong.
"What we did in truth was allow David Silva too much room in the first half. He completely dominated the game, controlled the game and I take responsibility it's not the players."
Pulis also revealed that he hopes to make more signings before the transfer window closes in three weeks' time.
He added: "The chairman has been very good. We are after quite a few targets and there will be players that leave the football club as well. We have to make sure we do our business without anyone else knowing and get it done. Hopefully we will get it done."
Albion, 1/1 to be relegated this season, visit Watford on Saturday and are 1/1 to beat the Hornets 2-0 and 1/1 to draw 1-1 at Vicarage Road.
