"A real negative today is the unfortunate incident (Bryan Oviedo's injury) and we need to give Bryan as much support as we can now," he told BT Sport. "He's had a terrific season and I've been very impressed with him. He's an important player in the group and he deserves a speedy recovery."
"We always looked a threat on the counter and a threat in front of goal," Martinez said on the match. "It was as good as it gets really in terms of a performance.
"It was a good cup tie, but the injury to Bryan affected everyone. Those types of injuries leave a sick taste."
Steven Naismith scored twice for Everton in their win at the Lamex Stadium.
