The winger is out of contract in January and is yet to sign a new deal.
His performances this season have seen fans calling for the 22-year-old to sign a new contract, while manager Darrell Clarke has confirmed negotiations have been ongoing for weeks.
But with the clock ticking until the end of his deal, McDonald is staying tight-lipped over his future.
When asked for an update he hesitated and said: “We’ll see.”
But he insisted that he wants to stay with the club.
“Of course (I want to stay),” McDonald added.
“I like playing for Walsall.
“I want to continue playing my football and I just give my best for Walsall when I’m in the shirt.
“I’m just concentrating on the games.
“We’ve got a lot of games over this Christmas period so I just want to focus on my football, continue delivering for the team and continue improving.”
McDonald has scored five goals and assisted three in all competitions this season, proving to be a bright spark in Walsall’s attack.
After coming through the youth ranks at Birmingham City and then having a short spell with Yeovil Town, the forward believes he is now playing the best football of my career.
“You could say that (it’s my best football),” he said.
“I feel comfortable and confident so I’m knuckling down, training hard and trying to improve every game.
“The fans are excellent, they’re always giving me confidence.
“Whenever I’m on the pitch they’re screaming, they’re loud and always give me that extra boost so I’m grateful for that.
“I’m enjoying it tremendously.
“I feel comfortably, I feel confident when I’m on the pitch, getting all the information from the coaches and I just want to soak it up and keep improving.
“The lads have been grafting in training, listening to instructions and we knew we could turn it around, we were just in a bad patch but we’re over that now and we’re looking to the future.”
