Eden Hazard is growing worried that Chelsea will block his move to Real Madrid due to their transfer ban.

Fifa's two-window suspension is heading to the Court of Arbitration for Sport — and defeat will stop the Blues using the Hazard cash for a world-class striker, says The Sun.

Chelsea will even weigh up keeping the Belgium star for the final year of his contract before losing him on a free in 2020.

Maurizio Sarri's squad have qualified for the Champions League and do not want to head into next season without a new No 9 as Gonzalo Higuain heads back to Juventus after his loan.

But getting banned from signing players until next year means keeping Hazard is a serious option, even if they miss out on a windfall for one of Europe's hottest properties.
