Arsenal are appealing a ruling made by the Court of Arbitration for Sport.

The Sun says the North London club have appealed against a ruling by FIFA which saw them handed a £33,000 fine — and the case will be heard next Tuesday.

It relates to sell-on clauses they agreed when selling players.

In 2018, they sold Chuba Akpom to Greek side PAOK and Joel Campbell to Frosinone in Italy.

Sell-on clauses were inserted into both deals stating PAOK would give the Gunners 30 per cent of any future fee for Akpom — but 40 per cent if he was transferred to a British club.

With Campbell it was 20 per cent to another side, but 30 per cent if sold back to Britain.

Akpom subsequently joined Middlesbrough last summer for £2.75million while Campbell is now playing in Mexico for Leon.

The FA and Premier League said no rules were broken but Fifa ruled the clause was illegal.

They claimed it amounted to third party ownership because it gave Arsenal power to influence transfer deals at another team.
