Arsene Wenger expects a quiet transfer deadline day for Arsenal, saying he is 99 percent sure the club will not make a last-minute signing.
Arsenal have signed Mohamed Elneny from Basel for £7 million but also had a number of players back from injury in January, leaving Wenger satisfied with the options at his disposal.
The only way Arsenal will conclude another deal is if a world-class player unexpectedly becomes available.
Asked if he was 100 percent sure there won't be another signing, Wenger said: "A hundred percent is difficult to say, 99 yes. A miracle can happen, somebody can knock on your door. If [Lionel] Messi knocks on my door at 10 to six tonight, I will not say please go back to Barcelona."
Since that scenario is fairly unlikely, that leaves only outgoings for Arsenal and the club is still working on a deal for right-back Mathieu Debuchy to go out on loan until the end of the season.
Debuchy has been frustrated at his lack of playing time at Arsenal and wants to stake a claim for a spot in France's European Championship squad.
Debuchy has been given the go-ahead to leave, but has yet to find another club and now faces a race against time before the window closes.
"Debuchy is still a possibility, yes. At the moment, it doesn't look like it. But it's still a possibility," Wenger said, adding that it was "too late to conclude a permanent deal."
Winger Serge Gnabry is also likely to be loaned out to a Championship club after being recalled from his unsuccessful spell at West Bromwich Albion.
Gnabry has struggled to even make the bench at West Brom, and Wenger said he is keen for the German to get regular playing time again.
"He's likely to go to a Championship club. We have to decide that today," Wenger said. "It's between two clubs. I want to give him some competition, because he didn't play at West Brom."
Wenger had predicted that this would be the busiest January window ever, but acknowledged on Monday that he'd been wrong about that.
"The whole period was much quieter than I expected. I thought there would be much more activity. But finally it's been really quiet, and the fact that we're all here [at his news conference] means it's still quiet," Wenger said.
"I'm one of the few who has done [business]. I never thought I would do much more, but ... I would have been open to one more. There is a rarity of players on the market, and it's very difficult to conclude anything at the moment."
