Robert Lewandowski's agent has warned Manchester United this client would not come cheap.

The Red Devils have been linked with the Bayern Munich striker following Robin van Persie's move to Fenerbahce but the Old Trafford outfit would have to shell out for his services according to Poland international's representative Cezary Kucharski.

Kucharski told Polish TV: "I think it would have to be a very high offer, definitely higher than £35m for Bayern to consider selling.

"Robert is one of the most valued strikers on the market who guarantees goals, guarantees assists, excitement. He has shown that over many years during his career.

"Every year he is an even better player and plays at a higher level and that is very important for other clubs because he has credibility and guarantees at least 30 goals a season.

"With a player of Robert's class, the truth is that not a lot of work is required because really there are only two directions in which he could go in the future, England or Spain, and only with Bayern Munich's acceptance."
