Sporting CP coach Ruben Amorim admits he's upset with the sale of Matheus Nunes.
The midfielder left Sporting this week for Wolves.
Amorim said, "I'm dissatisfied. If I lost a player like Matheus and I wasn't dissatisfied, something would happen to me. Regarding heartburn, the mister Sérgio Conceição, even with the titles and being national champion, is always having much more heartburn than I am. We have different personalities.
"I'm not happy, I didn't expect to lose him. But now it's time to prepare for the next game.
"We're not going to spend Matheus' money. He was sold to cover basic things for the club. We're not going to spoil that financial comfort to the management and we're not going to make big changes. It's difficult to sign at this time, clubs don't want to lose the best players."
