Cavani came to Old Trafford in the summer to strengthen Manchester's attack. He has played in 15 games so far and has scored five goals. It seems that his physical condition is gradually improving and he wants to be on the field for more minutes.
"I'm feeling in good shape fitness-wise and, as I wrote on social media, I was very happy and pleased to
have finally scored my first goal in the beautiful stadium that is Old Trafford,
" the former PSG striker told United's official website.
"As we all will know, I would genuinely have loved the supporters to have been in the stadium to enjoy the moment, but that's just how the circumstances are right now and dictated how it had to be.
"That first goal had been proving to be a bit elusive, with the post intervening on one occasion and the ball just not wanting to go in on another. But after a lot of effort, commitment and desire to succeed, the goal finally came and I was really happy, I really was!"
The South American played just 45 minutes against Southampton but scored one goal, and when he was substituted, Manchester United were 4-0 ahead of the Saints.
Cavani added: "
I think that right from the start of the game, you could almost breathe it in the air that the team were in decent nick
"Then when the Southampton player was sent off, that definitely opened up a bit more space for us. Although huge credit should also go to the team for how well we worked and moved the ball around to pick just the right time to attack.
" We managed to score the goals which made things more comfortable and allowed us to manage the game in a different way.
"Then for the second half I got to watch the game from the stands and follow closely just how the team was functioning as a unit. It's always very pleasing and makes you happy to see everything flowing and working so nicely, and things going to plan.
"Throughout my career so far, I've seen games like this, and I've featured in one or two goal fests. There was one game I was involved in at PSG, against Troyes, where we won, I think it was either nine or 10-0.
"These are the things that football throws up from time to time. Things that you get the chance to experience and which surely remain etched in your memory as a sportsperson."
