Happy Birthday King Kev!
The 23-year-old Nigerian is yet to play for the club's new manager after missing his first four games in charge because of the African Nations Cup, and the fifth with an ankle injury.
Martins: "He did a lot for Newcastle and all the fans love him. That's why they brought him back here.
"They call him the king, so I think it is very good.
"It is very good for him as well, and the players are going to try to play for him and try our best just to make him proud.
"I am sure everything will be okay. Let's wait and see.
"I think Kevin is very busy at the moment, but he had the doctor call me to see if I am okay.
"Everything has changed. We have a new manager and he will have changed a lot of things.
"It is not a problem for me to go back and focus on starting playing."
