Jussi Jaaskelainen believes Bolton's squad is deep enough to handle the possible January departure of Gary Cahill.
It is looking increasingly likely that England centre-half Cahill will be on his way out of the Reebok Stadium during the winter transfer window.
Chelsea have already admitted to holding an interest, while Arsenal are known to be long-time admirers of the former Aston Villa man.
With his contract with the Trotters running down, Owen Coyle is expected to cash in rather than risk losing a prized asset for nothing in the summer.
Cahill's departure would be keenly felt by Bolton, as they continue to languish inside the Premier League relegation zone, but Jaaskelainen insists they have enough about them to haul themselves clear of trouble.
"It would be a massive blow to lose Gary," the Finnish goalkeeper told the Bolton News.
"He is a great player and a great asset for the club. Unfortunately, his contract is running out.
"Whatever happens, happens, but hopefully it's the best for him.
"(David) Wheater played well before he was suspended and we have to believe we have got good enough players to turn things around.
"I personally think the squad is strong enough as long as we stop those mistakes we have been making at the moment."
Jaaskelainen and Cahill have formed part of a back four that has conceded 41 times in 18 games this season, and the Trotters are aware that they need to tighten things up if they to start moving in the right direction.
"We only have two clean sheets and that's not enough," added Jaaskelainen.
"Ideally, you want to build on clean sheets and hopefully nick a goal from someone else's mistakes.
"It's going the opposite way at the moment. We are the ones making mistakes and eventually the ball ends up in the net.
"We need to get two or three wins on the bounce.
"If you look at the Wolves game (on New Year's Eve) it is massive, as is the game at Everton the week after because we have got the big teams coming up. So, the next two games are crucial."
