Mircea Lucescu has urged Douglas Costa to join Juventus during the close season should he decide to leave Bayern Munich.
Lucescu brought the 26-year-old to Europe in 2010 when he was in charge at Shakhtar Donetsk, Costa playing over 200 games for the club before moving to Bayern in 2015.
"He's a great player and a good lad, but he needs an environment that stimulates him," the Romanian told Tuttosport.
"If you ask me, I'd tell him to go to Juve.
"That's because Serie A remains one of the most complicated leagues tactically. In the Bundesliga, all the teams play the same way, while in Italy there's great variety.
"That variety forces players to improve and develop. I think Douglas Costa at Juventus would take a definitive leap in quality, but don't let me manage the market.
"He can play anywhere, even as a central 'trequartista'. He's a tactical player, suitable for Italy."
