The 2021-2022 season has begun and that's the only thing fans seem to care about right now. The UEFA Champions League and the major European leagues are underway and there won't be room for transfer moves until January.

However, scouts and club hierarchies may not only focus on the current season but they might think about the long term as well. PSG, Real Madrid, and Juventus are reportedly keeping an eye on a Chelsea star's situation.

The Blues were crowned continental champions a few months ago and their players' stocks have significantly risen since then. One of their key players has entered the final year of his contract but his renewal doesn't look easy, as he asks for a £200,000-a-week salary ($275,900).

Chelsea center-back on the radar of PSG, Real Madrid, and Juve

Following a memorable UCL triumph, the Blues have reestablished themselves as one of the strongest teams in Europe and they plan to build from there. This summer, they landed Romelu Lukaku aiming to have another epic season.

However, Chelsea are also preparing for the future and that includes Antonio Rudiger's renewal. The center-back, who thrived under Thomas Tuchel, runs out of contract next summer and his potential free agency status has attracted interest on the continent.

Rudiger, 28, believes this could be his last opportunity to sign a lucrative deal. According to ESPN, he demands double his current wage to extend his contract, but Chelsea wouldn't go higher than £150,000 ($206,925).

Real Madrid, PSG, and Juventus may have taken note of this situation. Needless to say, landing a top center-back such as Rudiger for free is more than appealing in times when transfer fees are ridiculously expensive.
