Robins, who felt Albion's opening goal was offside, said: "I am over the moon with the players but really disappointed at the end because we gave them a really good game.
"We got our noses in front and then proceeded to stop defending. That is the nit-picking side of it.
"The other side was that was that we passed the ball well, created chances, scored great goals, made them look ordinary at times and that is testament to the character of the players.
"I have said to the players that they should come out of the game with plenty of confidence because those Albion players were in the Premier League last season."
