The Ladbrokes Premiership’s bottom club are understood to have agreed a fee with Burton for striker Liam Boyce and are closing in on his signing.
The 28-year-old former Ross County forward has netted 14 goals for Burton this season but his contract is due to expire in the summer.
When asked if he expected two new players – including Sibbick – Stendel said: “I hope so.
“You can see, especially in the last third, we need some different players.”
Meanwhile, former Hearts midfielder Glenn Whelan has signed for Joey Barton’s Fleetwood after his Tynecastle contract was terminated during the winter break.
