Chiellini’s agent, Davide Lippi, attended the Manchester derby on Tuesday and was invited by both clubs.
But Lippi also admits he is in talks with Spurs over a move.
“I was there but it was absolutely a courtesy visit,” Lippi told Sky Italia.
“I was invited by the two clubs and I was pleased to see a good match. The market is open all year, talking with everyone and everything, not just Chiellini.
“A real interest? It is normal when we talk about a very important player like Chiellini, but there is no news.
“There are many players that may interest Manchester City or the United, today I was talking to the leaders of Tottenham.”
