"I’m hopeful of at least two signings in the front third in the next week.
“We get bombarded in January with opportunities. Some exciting potential but I don’t want to speculate too much.”
However, speculation has surrounded the future of talented playmaker Anthony Caceres, with the player reportedly attracting interest from the City Football Group.
The CFG owners of rival A-League club Melbourne City, New York City in the MLS and EPL powerhouse Manchester City.
Walmsley was surprised to have heard the rumour, but confirmed the interest.
“I know Mike Charlesworth [Mariners chairman] has been in dialogue with the City Football Group," Walmsley said.
"And Caceres has got a transfer fee built into his contract.
“And if Mike and the head of the City Group have come to an agreement I’ve yet to be told that.
“If it is [true] what a great opportunity for Caceres to try reach the potential we all think he’s got.
“And I’m sure any deal stuck with Mike will look after the club’s best interest but hopefully it can be resolved quickly we can move into the transfer market and do a great job for the Mariners.”
As for team news ahead of Friday night’s clash with Victory in Geelong, Walmsley confirmed 21-year-old striker Josh Bingham will replace suspended Roy O’Donovan up-front.
Keeper Tom Heward-Belle is likely to retain his spot and new signings Francesco Stellar, Trent Buhagiar and keeper Ali Bray should also be in the squad for the clash at Simmonds Stadium.
Walmsley described the pacy Buhagiar as an attacking weapon he simply could not overlook for this game.
