Steve Cotterill eyed his January shopping budget and warned Pompey fans: Don't get excited.
The Blues boss has been told he has a 'little' money to spend by joint-owner Balram Chainrai to boost his dilapidated squad in the current transfer window.
Cotterill looks set to operate within the loan market again this month and will be able to make two additions on that front after Liam Lawrence's signing became permanent.
Matt Ritchie is set to join Swindon for an initial 200,000, rising to 250,000.
The Pompey boss will have that to reinvest but he knows there is not going to be major cash to splash to assist a charge at the play-offs.
Cotterill said: 'We shouldn't be thinking we're going to be spending big.
'If we do any buying it will not be anything significant.
'We can't get our heads in the clouds thinking this one or that one is available.
'If there's money available I'll be spending it – don't worry. That's not because I'm a spend thrifty manager. That's not the case. But we need to bring in players.'
Meanwhile, John Utaka has been linked with a move from Pompey.
Turkish side Konyaspor have indicated they are keen on taking the Nigerian away from Fratton Park.
Konyaspor president Bahar Karapinar has made clear his club are keen on the 28-year-old.
Utaka arrived from Rennes for 7m in 2007 and has made 110 appearances for Pompey, scoring 11 goals in his time at the club.
West Ham have also been linked with a 4m move for Liam Lawrence, after his loan signing from Stoke became permanent on January 1.
