Rio Ferdinand has advised Antonio Rudiger against leaving Chelsea for any other European club.
The Manchester legend reminded Rudiger that he has more chances of winning the Premier League and Champions League at Chelsea than any other club.
He said that neither Barcelona nor Real Madrid could offer the German the opportunity he has in the current Chelsea under Thomas Tuchel's supervision.
Ferdinand told Rudiger, who has refused to extend his contract at Stamford Bridge, to commit his future to Chelsea, insisting there is only one club in Europe he can see the Germany international being tempted to join.
Rudiger has emerged as an essential component of Tuchel's near relentless winning machine, and being seen by many as Chelsea's best player so far this season.
The German is currently in the best form of his career and has a number of Europe's top clubs monitoring his situation with talks over a new contract having stalled.
Chelsea are believed to be reluctant to cave into Rudiger's demands, with the player looking for a salary in excess of £200,000-a-week.
Asked what he would do in Rudiger's position, Ferdinand said, "I'd stay," According to Metro.
"I'd sign because you've got a genuine chance of winning the Premier League and European competitions.
'Tuchel came in and changed the fortunes of all those players' lives. They won the Champions League immediately and I watched Chelsea last weekend and they're formidable.
"They are a team. Rudiger's playing the best football I've ever seen. As a player do you risk changing that, and risk a downturn in form and performance and risk it by going somewhere else. I only see Bayern Munich as being on the same level. I think Bayern Munich are above Chelsea.
"But if he goes to Bayern Munich he's going to be in a genuinely important league and he's got a chance of winning the Champions League with the players there.
"I can't see him going to Real Madrid and Barcelona where the teams are in transition. If you're looking at the Champions League, they're behind Chelsea and Bayern Munich.
"I was offered to go to big clubs during my Manchester United career but I stayed based on the fact I thought I had more chance of winning the Champions League and league titles at Man United than at the other teams."
Rudiger, who has featured in almost all Chelsea's games this season, will hope to continue in his fine form.when the Blues tackle Manchester United at Old Trafford at the weekend.
Both teams were successful in their Champions League outings on Tuesday with Manchester United beating Villarreal 2-0 in Spain while Chelsea thrashed Italian giants, Juventus 4-0.
