The 24 year-old got off to the perfect start on his return from injury, finding the net after just ten minutes against an in-form Oldham side.
The Sunderland-born front man then went close to doubling his tally when he found the roof of the net and fired narrowly wide shortly after.
But The Saddlers saw their one-goal lead overturned and came away from Greater Manchester with nothing to show for our efforts.
“For me, I’m over the moon to score my first League goal but on the flipside we’re hugely disappointed to have lost the game, especially after going a goal up,” he said. “Its been ten weeks out for me and to get a goal so early in my first start, you could see in my celebration all those frustrations just came out at once.
“Its annoying because you look back at the game and think we could have got something out of it and we got done by a deflected goal.”
Now all attentions turn to Saturday’s home game with Crewe Alexandra and Cook insists his team-mates are eager to bounce-back.
“I have no doubts that we’ll go again,” he added. “We’ve got a great bunch of lads and it hurts when we lose, which is a massive thing for me because I can see how much it means to us.
“We’re looking ahead to Crewe now, they are another team who look to play the right way, bringing through players from their Academy.
“We have to draw a line under the Oldham result and push on at the weekend.
“We have to make sure we get three points are start to move up the table.”
