West Brom manager Carlos Corberan told BBC Radio WM:
"We made some good pressing and scored the first goal from one of those pressings, and our second half was much better, more aggressive and showed a lot of personality to score the second goal.
[On Diangana]: "Grady is a very special player and if he finds consistency it is very positive for us.
"The important thing for me is creating chances and scoring goals but today Thomas-Asante didn't score but was excellent, one of his best games I have seen him play this season."
Hull manager Liam Rosenior told BBC Radio Humberside:
"It's always horrible, especially when you lose a game in the manner that we did. We gift-wrapped the game to them.
"For 90% of the game we were the better team but in the 10% where we switch off and make errors and don't do professional things, that's what won them the game.
"We've gone toe to toe (unlike Connolly) with a very good team, dominated certain areas but gifted goals at crucial times.
"(Seri) has made a mistake and will hold his hands up and I will hold my hands up because I'm asking the players to play that way - I believe in it.
"In fact, playing that way gets us back in the game and we took complete control, Lewie scored a fantastic goal and for a 15-minute spell in the second half we were completely on top."
