RB Leipzig defender Dayot Upamecano has been advised not to leave the German club without guarantees over playing time amid interest from Chelsea.
Premier League rivals Arsenal and Manchester United are also interested in the 21 year old defender.
“I see him at every big club when he gets the game practice,” former Bayern Munich midfielder Lothar Matthaus said on Sky Sports’ Heart of the Team podcast.
“If he changes, he should also be convinced that the coach or club gives him the confidence that he plays regularly – as is now the case in Leipzig.”
The World Cup winner added: “He is a young player, he is highly talented, he has good conditions, is fast, has a good positional game and he uses his body well for his 21 years.
“He is very far for his age. Even a year or two in Leipzig would not hurt him, because Leipzig is now a top team. They’re in the top eight in the Champions League.
“I can still see one or two percent where he can learn: from the position game, from the opening of the game. But as I said, he’s a huge player and that’s why I’m not surprised that the top clubs in Europe are after him.”
Upamecano reportedly has a €60m [£52m] release clause in his current Leipzig contract.
