Sevilla coach Michel has criticised Esteban Granero for flirting with the Liga club during the recent transfer window before finally signing with Premier League side Queens Park Rangers.
Granero, 25, joined Mark Hughes' QPR revolution at the end of August after signing from Real Madrid in a £7 million move.
But Michel believes the deal only took place after Sevilla had been used as a pawn in the negotiations.
"Through a player of Real Madrid, Granero made contact with me and I related the situation to (Sevilla sporting director) Monchi," Michel told Sevilla's TV channel. "But in the end he took the decision not to come here. If I were Granero I would have decided to play for Sevilla. I felt used."
With Real Madrid visiting the Estadio Sanchez Pizjuan on Saturday, Michel said he had no divided loyalties at all and hoped for three points to continue Sevilla's decent start to the season.
"On Saturday we are all sevillistas looking to win this game," he said. "I would give all my contract in order to beat Real Madrid. A win would be fantastic for the rest of the season. I know this team has the resources to get back to where it was a few years ago, not where it was last year."
Having taken the job on a temporary basis last February, Michel guided the team to a disappointing ninth placed finish, but said he had no doubts about signing a permanent deal in the summer.
"Knowing this city and this club I wanted to stay on," he said. "It is the ideal place to develop my idea of football. It is not easy to find a club where everyone is willing to work with you."
Sevilla centre-forward and captain Alvaro Negredo spoke last week about problems within the club's dressing-room last season. Michel admitted things had not been ideal, but the atmosphere around the camp was much better now.
"I arrived at a team which was down, sensitive and hurting from bad results," he added. "They have put in a huge amount of work. I wish that now they can bring to the field the positive mood that can be seen now at training."
The Sevilla boss also spoke about attacker Jose Antonio Reyes, who has yet to reach the heights of his first spell at Sevilla since a €3.5 million return from Atletico Madrid last January.
"He is making a big effort to fit into the system," Michel said. "He is working hard and training well. We may have to play him in positions that are good for the team but not so much for him. It seems to me that he is happy to do that."
