Keates, who had watched his side suffer just their second defeat of the league campaign, agreed that the Saddlers were not good enough as they failed to make anything out of their attacking opportunities during a frustrating afternoon at Banks's Stadium.
Speaking via the Express & Star, Dean said; "You can’t give a team a head start and we gave them a head start in the first couple of minutes. We weren’t good enough after that.
"The keeper pulled off some decent saves for them but that’s football. With the penalty – it was that second phase. We were aware of it. We told the lads to be aware of every set piece and we got caught flat-footed.
"After that it was a little bit scrappy. The final product wasn’t good enough and when we did get through their keeper pulled off some decent saves. We are disappointed.
"We don’t like losing games. We got a reaction after the Doncaster game and we will be looking for one on Tuesday against Shrewsbury."
