Thomas Tuchel said he will "sleep well" once Paris Saint-Germain sign a new player during the transfer window as he eyes reinforcements.
And Tuchel admits the difficulty of landing new players during the winter has him nervous.
"But, in the same time, I'm afraid [of not having one]. I know that the transfer window in winter is complicated.
"I hope [a new player will arrive], but I'm scared too [to not have him]. When I get this recruit, I'll sleep well."
PSG bounced back from their shock Coupe de la Ligue elimination by defeating 10-man Amiens, despite the absence of superstar Neymar.
Neymar – who has been linked with a sensational return to La Liga champions Barcelona – was rested but PSG still reigned supreme thanks to Edinson Cavani and Kylian Mbappe after the midweek defeat to Guingamp.
"It was the best answer, and necessary. Against Guingamp, it was weird, but we lost it," Tuchel said. "We missed some things and today we have played with a lot of qualities mentally.
"We started strong for 30 minutes, then we lost a little bit, and in the second half we exchanged [Julian] Draxler and Dani Alves, that was very good, and I'm very happy. It's our challenge to find the solutions against defensive teams, but there's been a lot of effort.
"Sometimes it's hard for the team to win all the time and stay focused. It's like that in a big club, but it's never easy to find the motivation. The team showed it all season and Guingamp was an exception."
PSG return to the pitch next Saturday to face Guingamp, with the Paris side looking to extend their sizable lead atop the Ligue 1 table.
