The 21-year-old full-back has recently signed a five-year deal at White Hart Lane, and despite leaving the Liberty Stadium, he continues to hold high expectations for his former team and their prospects under current manager Garry Monk.
"I have got no doubts Garry is the right man to take Swansea forward," Davies told the South Wales Evening Post.
"It was a pleasure to play under him and it was difficult for me to leave with him in charge.
"I think Swansea will do well under him.
The Swans achieved a 12th placed league finish last season, in what proved their most turbulent of their three campaigns since promotion to the top flight.
Following Michael Laudrup’s sacking in February, Garry Monk took the reins as interim player-manager, and having guided the club to safety, the Englishman was offered the managerial position on a permanent basis. He subsequently put pen to paper on a three-year-deal.
Davies continued his praise of Monk, suggesting the side could show concrete signs of improvement next term, despite the loss of key players. As well as the Welsh full-back, Swans fans have been forced to witness the departure of the Michu and Michel Vorm, the latter of course has also completed a switch to White Hart Lane.
Nonetheless, the club have utilised the current window in order to make significant upgrades amongst the playing staff. The recent double signing of Gylfi Sigurdsson and Jefferson Montero has made the squad look considerably stronger, whilst Monk has also finalised moves for Marvin Emnes, Lukasz Fabianski and former Lyon striker Bafetimbi Gomis
"They have made some good signings and because the players know Garry, they want to do well for him. Some players could be put out if they think some of their team-mates are close to the manager, but it is not like that at Swansea,” said the Welshman. "The squad is looking really strong now.”
"Everybody's heart is with Garry and everyone wants to put their body on their line to do well."
"When you look at it, I don't see any reason why Swansea can't push into the top half again next season."
