Sunderland have sealed a deal to sign young Chelsea striker Marc Guiu on a season-long loan, with the move now in the final stages of completion.

The agreement is for a straight loan with no option to buy, as Chelsea view the 18-year-old Spanish forward as a key part of their long-term plans at Stamford Bridge.

Guiu’s full salary will be covered by Sunderland, underlining his importance to new manager Régis Le Bris, who sees the powerful centre-forward as a vital part of his attacking setup for the upcoming Premier League campaign.
