Carvalhal said: “Christmas was a little strange. I was in Sheffield with my wife and son. I used a lot of the phone that night. We live in the global world at this moment.
“I received calls to work from Japan, Turkey, the United States and other countries far away, as well as England. It
was a strange day because I was on phone a lot. But that is the life.
“We are professionals. We agreed on Wednesday night and it was thought I would watch the games against Watford and Tottenham and then start working with the team next week.
“But I said exactly the opposite. I said I wanted to go to Swansea the next morning to prepare the team.
“We got up at 4am and travelled to be with the players at training on Thursday because time is our enemy at the moment.
“We worked hard in those two days to analyse and give confidence to the players. We explained to them exactly what we want.
“It was an important small step in a very difficult job in hand. Transfers? I haven't even had time to call home to my family!
“This moment as you understand, it is a new club, you check your players one by one, the previous game, prepare the game, analyse Watford, everything in 48 hours."
