The Blues currently have only one fit senior keeper in Joel Robles, with the Spaniard deputising in the absence of usual number one Tim Howard.
That has led to them relying on academy 'keeper Russell Griffiths to provide back up to Spaniard Robles, and Martinez has admitted that Howard’s injury, which will see him out until mid-February and beyond, has left his side short on numbers in that department.
However, the Catalan manager refuses to be forced into a panic buy, with the January transfer window coming to a close on Monday.
“The situation hasn’t changed,” Martinez said.
“Tim Howard will be out for the period I expected but I will always keep an eye open to see if we need to do anything. But we would not just bring anyone in. They need to be the right personality to fit into the squad.”
Martinez has already said to the Liverpool Echo that he is looking to make a signing for the long-term, and revealed that he has “made enquiries” but his side are no closer to wrapping up a deal. He also insists that unless the “right personality” emerges then he is happy to wait until the summer.
The manager has also praised the performances of deputy Joel Robles, with the Spaniard growing in confidence and producing a number of top saves in the recent FA Cup loss to West Ham.
“It has been good to see Joel so influential in the last two games,” added Martinez.
“In goalkeeping terms he is still a young man and so he is only going to become a stronger goalkeeper.”
