Manager Phil Parkinson says retaining loan signing Arthur Okonkwo is "massive" for Wrexham as they continue their push for promotion.
The 22-year-old goalkeeper signed a season-long loan from Arsenal last September.
The deadline for Okonkwo to be called back was 21 January and when no call came, Parkinson admits relief.
"It's a massive signing for us to keep Arthur, he's been exceptional for us," he said.
"He's a great lad and has bought in to everything the club is about. He's moved up here and he's been great to have around, but not just that, he's a terrific goalkeeper.
