Sacked Swansea City coach Gabriele Ambrosetti has retweeted messages slamming the club for changing the management team.
Head coach Francesco Guidolin and his backroom staff were relieved of their duties on Monday, with American Bob Bradley immediately coming in as a replacement.
After the Swans' opening-day victory at the start of the season, the club recorded five defeats and a draw in the Premier League before Guidolin's dismissal.
On Twitter, Ambrosetti wrote: "I'm sad, but I want to thank everyone - the club, the players and the fans. You have made me feel at home. You taught me what is Wales and what it means to be Swans.
"I loved everything - the shirt, the stadium, the city, even the rain. For these reasons a part of my heart will always remain Jack."
The coach went on to retweet fans describing the club as "disgraceful" and "stupid", while one message claimed that Swansea's new American owners are "ruining" the Welsh outfit.
