Incoming Manchester City manager Pep Guardiola will not be allowed to sign any of his former Bayern Munich players, according to Douglas Costa.
The Spanish boss is expected to have a hefty transfer kitty when he arrives at the Etihad Stadium, but none of that cash will be spent on luring Bayern's stars to the Premier League.
Costa, who was signed by Guardiola last year from Shakhtar Donetsk, has revealed that the 45-year-old has a clause in his contract preventing him from poaching players at the Allianz Arena.
"Would I be open to City if Pep called? It's something he has in his contract, a clause that says he cannot sign any players from Bayern," Costa told Globo Esporte.
"I'm in a situation where I could stay at Bayern for a long time. The club's philosophy is to keep players at Bayern for a long time. I'm happy at the prospect of enjoying a long career here."
Meanwhile, reports have claimed that City are in talks to sign Pierre-Emerick Aubameyang from Borussia Dortmund.
