An extra payment for Roma striker Tammy Abraham has been found in their financial accounts.

Roma initially paid €40m plus bonuses rising to €5m to Chelsea last summer.

However, Calciomercato.com reports Roma's accounts show an extra payment for Chelsea and Abraham's agent.

The installment is a rolling commission that is activated every six months.

It is reported to be worth €400,000 for six months, but it is not clear if this is going entirely to the agent or to Chelsea.
