Sean Dyche said he and his Everton players are used to facing challenging circumstances after it emerged the club could be hit with a second points deduction this season.
The Toffees were docked 10 points in November for breaking the Premier League's profit and sustainability rules that restrict how much money a club can lose over a three-year period.
Everton are appealing that decision, which judged they had breached the limit at the end of the 2021/22 season.
On Tuesday, Everton and Nottingham Forest were then referred by the Premier League to an independent commission for sanction after breaching the rules at the end of the 2022/23 campaign.
Both clubs are involved in the Premier League battle for survival and any further points penalties could have huge ramifications.
Everton responded to the 10-point deduction with a run of four consecutive victories to pull clear of the drop zone.
But they have since taken just one point from their last four Premier League games to sit just one point above the drop zone.
"My insistence is on myself, the staff and the players to stay focused on the job in hand, which hasn't changed at all," Dyche said. "We had a really great run of performances that got wins, and a good run of performances that didn't, but that's sometimes the Premier League.
Everton's issues date back to reckless spending during Farhad Moshiri's time in charge and the costs related to a new 53,000 capacity stadium.
The British-Iranian businessman agreed to sell his 94 percent stake in the club to US investment firm 777 partners in September, but the deal is still to be ratified by the Premier League.
