Real Madrid will insist on a buy-back clause in Martin Odegaard's deal with Arsenal.

Odegaard is reportedly poised to sign a five-year deal with the Gunners to keep him on their books until the summer of 2026, reports the Daily Express.

A relatively modest fee of around £30m is said to have been agreed between Arsenal and Real Madrid, with the player now in line to thrash out the formalities ahead of an official announcement.

Radioestadio reports the La Liga giants have moved to protect themselves with the shrewd inclusion of a first refusal clause in the framework of the deal, according to Radioestadio.

It is claimed that Real Madrid will retain this right in the event of a future sale, in which Arsenal would be obliged to notify them if an offer from another club is accepted.

The 13-time European champions would then have the option to match the bid and bring Odegaard back to the Bernabeu for themselves, or pass up the opportunity and allow the other club to progress with the move.
