The Toon striker has broken the silence to speak out against owner Mike Ashley.
He insists the players are 'shocked' and 'depressed' by Kevin Keegan's controversial exit.
Martins: "Yes I have been thinking deep about my own career. But I will never let that affect my game because I have to give my all.
"Everyone is entitled to their own decision and career. Events like this will only trigger speculation.
"If the players are determined to succeed they will not allow what just happened to bother them. But nothing will surprise me in the coming months."No one is happy about the situation but Michael has been rallying the players together.
"I know if we get other injured players back we can ride the storm and give the fans an opportunity to believe in this great club once more. We should focus on the games ahead.
"A place in the UEFA Cup is not beyond this club.
"Kevin's departure came as a rude shock. I don't know what led to it but it's a huge setback.
"For the fans it's a huge blow and you can see how they expressed their anger, putting the pressure on the owner.
"They truly love and admire Kevin Keegan. I feel so much for the fans because they don't deserve it.
"I don't know who's to blame. The only losers are the fans and the players.
"It's normal that players feel depressed. We all like him as a manager.
"In my opinion we have a good squad of players who showed against Manchester United that we can break into the top seven.
"Personally it has been frustrating for me as I've been injured. I'm just looking forward to getting back."
