Martinez is once again on the search for a new keeper after the injury blow that will sideline Dorus De Vries for two months.
Current cover for De Vries Artur Krysiak will deputise against Southampton on Saturday but Roberto wants cover again despite this factor.
Speaking to the Western Mail, Martinez admitted the extent of De Vries injury would keep him out for two months but he was confident that the on loan Birmingham youngster could do a job.
Martinez said โHe (Dorus) had his operation and went home afterwards and I am happy with that because now the recovery starts.
โThat should take between six and seven weeks but knowing Dorus he should be back before then because he is such a strong character and he will not want to miss out.
โArtur is first in line at the moment. I would not bring someone in who didnโt know the environment around him. He has been playing reserve football and working extremely hard and I am happy with him because that is why you have back-up goalkeepers.
โWe do need someone to come in because you canโt go with just one keeper for six weeks and we will look to do something before Saturday to give us strength in that department.
โBut I have no problem throwing Artur in, heโs a positive keeper who is very secure and has been waiting for his chance. I hope he takes it.
โHe has been impressing in training and now it is his opportunity because once you are on the pitch you have to make sure you are ready.โ
