The Italian was recently installed as the Swans top man to work alongside Alan Curtis and since his arrival, the Welsh club have secured two victories to move out of the relegation zone.
"It has probably been about a new guy coming in, everyone gets buzzing again looking to impress," said the Wales international defender.
"A new manager comes in and a lot of people liven up trying to impress him, that is only human nature. The players who want to get into the team want to show him what they can do.
"He has lifted the place a little bit and also tried to implement some of his own ideas into the team in the week he has taken training.
"I think all the lads have been impressed with his first week and how he goes about work and what he is asking of us so it looks good at the moment."
