The manager, who secured his first win as Saddlers manager thanks to an Alan Thompson own-goal, admitted that his team have been under plenty of pressure after failing to score a single goal in their four previous outings.
Dean, speaking via the Express & Star, said; "On the mental side it has been hard for the players. The recent results, that is a load they have been carrying. If players look on social media they will see their names coming up – we all know we hadn’t scored or won in four.
"That’s why we would have taken anything against Bury. It was about getting a result. With the position we are in, mental strength is massive. It’s not about performances now. It’s about getting points.
"The lads trained well last week, they were bright, sharp and moved the ball well. We had hoped that would have gone into the performance and it did in patches. But it was about the mental side, staying in the game, continuing to work hard and grinding something out and we did that. That’s why I was delighted with what we got."
Keates, who joined the Saddlers after a successful spell with Vanarama National League promotion-chasers Wrexham, went on to reveal that he will work hard with his attacking players over the next few days to give them a bit more belief as they look to build upon their first win in five outings.
The gaffer continued; "We got into some good areas against Bury but the final ball was not good enough or people were passing up opportunities to have a shot. I think that is maybe a little bit of a confidence thing.
"We could have made the game a little bit easier for ourselves, but we made the wrong pass or the cross wasn’t good enough. We will look at those things over the next 48 hours before the Oldham game."
