Town fitness coach Antonio Gomez has left his job at Portman Road to take up a similar role back home in Spain. Gomez, who also worked with Liverpool and Sunderland while in England, joined the Blues as part of Roy Keane’s backroom team in April 2009.
Gomez said: "I've been very happy at Ipswich and have really enjoyed working with the players and the staff here.
"This is a personal decision for me rather than anything else. I have just got married and my wife Natalie has a good job in Spain. I have been offered a fitness coach role at a club back home and the timing feels right to go back to Spain.
"I'm going to miss everyone at the club. I was made to feel very welcome here from the first day I arrived and it's difficult to say goodbye.
"I spoke to the manager before training on Monday and he was very understanding about it. I felt quite emotional during the session, knowing I was moving on.
"I want to say thanks to the manager, the staff, the players and everyone at Ipswich and I hope the club has a very successful season and goes on to win promotion to the Premier League."
Blues boss Paul Jewell added: "I've enjoyed working with Antonio and I'm disappointed to see him leave us but understand his reasons and I'd like to wish him every success in the future."
Gomez is the second fitness coach to leave the club this summer, Simon Thadani, who had been with the Blues since George Burley's time as boss, having been amongst the backroom staff who moved on at the end of the season.
