Chelsea defender Antonio Rudiger feels disrespected with the contract proposal on the table, according to Sport1.
The Germany international has entered the final year of his contract, and he has yet to commit to a possible renewal.
He is eager to earn £200,000-a-week with the extension, but the board have refused to meet his demands.
Rudiger is currently on £130,000-a-week, and the hierarchy are reluctant to offer him more than £150,000 weekly.
The centre-back has been a key player for the Blues in the backline this year, and he feels disrespected by the offer.
The defender has no plans of negotiating lower terms, and could walk away on a free transfer at the end of the season.
Real Madrid, Paris Saint-Germain and Bayern Munich could negotiate pre-contract deals with him at the turn of the year.
Tottenham Hotspur have also been linked with him in the past, but it is unclear whether they will re-enter the pursuit.
