Mikkel Andersen admits constant changes at Portsmouth are making life difficult for the League One outfit.
With there no money to spend at Fratton Park, Pompey have looked to make the most of the loan market this season.
Bringing in quality additions on short-term deals has its benefits, but Michael Appleton has been unable to name a settled side as a result.
Andersen concedes that instability can be hard to handle, but believes Portsmouth are still capable of pushing for promotion.
The Danish goalkeeper, who is on loan at Pompey from Reading, told bold.dk: "We had to say goodbye to a striker from Bournemouth (Wes Thomas) who had to return after a month-long spell.
"We got Scott Allan in from West Brom, which means that we have had to change our style again.
"We have had to rebuild for the third time this season, but I am optimistic. The season is long and anything can happen. It would be amazing to secure a play-off spot.
"We are not disappointed with how things have gone, but we did expect more.
"We have had a good run lately and then we ran into two difficult games against Stevenage and Sheffield United, but I feel we can still take positives from those games."
