Morgan Whittaker will be in Swansea City's squad to face Birmingham City this weekend, although Jamie Paterson will not be involved.
Whittaker was recalled from his loan spell with Plymouth Argyle last month and was the subject of fierce transfer interest from Rangers.
However, the Scottish Premiership giants failed to meet Swansea's valuation of the player, meaning the 22-year-old will now spend the remainder of the campaign in south Wales.
"The whole thing about Morgan, it’s so frustrating because I've got a brilliant relationship with him," explained Martin.
"I hope that’ll show in the next three months. I’ve never been anything but honest with Morgs. He understood why I wanted him to go out on loan and play football.
"The amount of work Josh (Marsh) put in to find him the right club, support network and to stay in contact with him, there’s been a lot of work put in.
"He’s come back and not been frustrated with me because I didn't make the decision to call him back. Again, it’s not in my control. The decision was made so we have to deal with that.
"He’s given us absolutely everything he’s got since he’s been back. He’ll be in the squad tomorrow. All the nonsense is done.
"I’ve had Rangers fans message me on Linkedin saying ‘let him go’. I’d like to reiterate to them, ‘I apologise I was crap at your club, but I don’t have control over Morgan Whittaker’. That’s where we’re at."
Paterson is another player who could well have left the Swansea.com Stadium last month after being told that he was no longer in Martin's first team plans.
But the attacker failed to find a new club and also remains with the Swans, but will not be in the matchday 18 against Birmingham, with Martin stating the 31-year-old's situation is unlikely to change in the near future.
"We haven’t had a real deep chat about it yet," explained the Swans boss. "The situation is the same. There might be an opportunity that arises for him at some point. In the short-term, I don’t see it changing.
"The players we’ve got in the squad, the people that give us absolutely everything, that’s where it’s at. It’s down to Pato. He won’t be in the squad tomorrow."
The January transfer window proved to be one of huge frustration for those on the ground at Swansea. A total of six players left the club and not a single signing was made, leaving the squad in a weaker position than it was before the window opened.
The Swans were on the brink of signing Karlan Grant on loan on deadline day, although West Brom pulled the plug on a deal after they failed to recruit Omari Hutchinson on loan from Chelsea.
Speaking in an interview with the club's Supporters' Trust after the transfer window, co-owner Jason Levien stated that Grant was set to be made the club's highest-paid player.
"We ultimately had a player who we agreed terms with, who we were told the club agreed to terms with, who would have been the highest-paid player on the squad on a weekly basis, who had a prolific goal scoring track record in past years," the American said.
"But we went to the deadline and, literally as the moment the deadline hit, the other side decided it wasn't the right decision which was outside of our control."
And Martin stated the Swans were only in the running to sign Grant after head of football operations Josh Marsh "pulled a rabbit out of the hat" in the final throes of the window, with the boss adding that other targets offered far better value for the club.
"We were only going to do business on the final day because of Josh, because of his relationship with Karlan Grant, with Carlos Corberan and with the agent, because he played a part in signing Karlan Grant [at Huddersfield]," he added.
“We were going to pull a rabbit out of a hat because of him. We didn’t because when you leave things that late it’s really dangerous.
“I don't know the financial details, that’s not my job, but that wasn’t the plan. It wasn’t that we worked on him four weeks, five weeks, three months.
“Something came up and Josh managed to get on it, but I'm pretty sure that wasn’t anyone’s plan to pay one player – if that’s true, and I have to trust Jason on that one - that much, because that’s not how we work here really.
“There were a lot of players who were discussed that were far better value to the club short term, medium term and long term.”
And when asked if multiple players could have been recruited for the fees discussed on the collapsed deal for Grant, Martin said: “Yeah I think so, yeah."
