Former Manchester United midfielder Bastian Schweinsteiger says Sasa Kalajdzic isn't ready for a Premier League move.
Stuttgart striker Kalajdzic has been linked with Schweinsteiger's former clubs United and Bayern Munich.
He said: "I have a high regard for Sasa.
"(He is) a slightly different centre-forward, not done developing yet.
“Now he has to reach the next level, but from my experience, maybe the jump would be too big."
