Mauricio Pochettino said Paris Saint-Germain should be left to work on signings "in silence" amid Barcelona's anger over Lionel Messi.
Barcelona coach Ronald Koeman hit out at PSG on Wednesday, saying the Ligue 1 giants had been "disrespectful" by regularly discussing Messi.
Angel Di Maria became the latest person connected to PSG to discuss Messi, with coach Pochettino, sporting director Leonardo and Neymar having also spoken about the Argentina star in recent months.
Pochettino would not be drawn into discussing Di Maria's comments about Messi, who is out of contract at the end of the season.
"I am not going to talk about what our player's comment, as you know, because my words can be misunderstood, and then these words can go to another country in another way," he told a news conference after a 3-0 win over Nimes.
"I have to be focused on trying to improve this team, from now to the end of the season, to try to achieve our goals, knowing that it is not going to be easy because we are in a difficult competition, in a weird situation, with the pandemic that it is affecting all of us, and also football.
"And then, the Champions League and Coupe de France, we will try to compete and go as far as we can, try to win, because in Paris, is all about to win.
"But I don't want to give names, don't want to think on the future. I'm sure that the club is working in different situations to improve. So let's leave the club working in silence, in secret, in order to have a better team and with more possibilities to win."
Di Maria opened the scoring in PSG's win over Nimes before goals from Pablo Sarabia and Kylian Mbappe.
Pochettino praised the performance of Di Maria, who is also out of contract at the end of the season.
"I'm happy with [Di Maria's] performance and compromise within the team," he said.
"I think that as every player, he needs time but Angel is a very important player for the team. He's been at this club for many years. So I'm happy for his goal and his performance."
