Marcus Bean is targeting a Fratton Park stay beyond his initial loan.
And the midfielder has three more games to convince Andy Awford he is worthy of remaining.
The 30-year-old’s Colchester contract expires in the summer, leaving him contemplating the possibility of needing to find a permanent employer elsewhere.
He has impressed since linking up with the Blues on loan until January 3.
With Tranmere’s FA Cup exploits forcing the cancellation of the fixture scheduled for that day, Bean now has three matches remaining.
They are Cheltenham tomorrow followed by AFC Wimbledon (Boxing Day) and Luton (December 28).
And Bean is seeking to maintain his form to have a chance of securing a move.
He said: ‘Pompey have given me an opportunity and I am grateful for that.
‘I had been waiting quite a long time to go out on loan and they showed a lot of faith in me. I am here to try to repay it.
‘We will see what happens, I haven’t really spoken to anyone at Colchester as I really want to focus on my business on the pitch.
‘Nothing can be done now anyway, closer to the time we will reassess the situation.
‘I would rather have my future sorted before going into the mad rush of the summer.
‘If I can sort it out beforehand then that would be great but I won’t be panicking or getting silly.
‘And with three games left I want to do as well as I can at Portsmouth.’
Meanwhile, the visit of Tranmere has been rearranged for Tuesday, February 24.
