The souring of Carlos Tevez's relationship with Manchester United has been underlined by the Argentinian's revelation that he will enthusiastically celebrate any goals he scores against them in the future.
Now at Manchester City, Tevez won widespread praise for his discreet acknowledgements of his two goals in Monday night's 3-1 win over West Ham, the club that brought him to England.
Tevez was given a warm reception by the travelling Hammers fans, who remember him fondly for his role in keeping the east London club in the Premier League in 2006-07.
United's fans also took Tevez to their hearts during his time at Old Trafford but he was dismayed by the hostile reaction he received from them on his return for the Manchester derby earlier this month.
"I decided not to celebrate my goals out of respect to West Ham," Tevez said. "They were my first club in England and, in my heart, part of me will always be a Hammer.
"The professional part of me was really pleased with my first City goals at home but, personally, I would have preferred to beat another club.
"In the derby against United I had also decided not to celebrate our goals but, after the bad treatment I received from the supporters that day, I have changed my stance on that. If I score in the next derby then I am sure that I will celebrate."
