Sunderland have confirmed that Atletico Madrid right-back Javier Manquillo is currently undergoing a medical at the Academy of Light, meaning that he will become the club's sixth summer signing barring any late surprises.
Brief stint in Liverpool introduced Manquillo to England
The player was rumoured to be in talks with the Wearsiders in recent days, but this is the first official confirmation that a deal is nearing completion. Assistant manager Paul Bracewell took up media duties after Sunderland's 1-0 win over Shrewsbury in the EFL Cup second round, and he broke the news of Manquillo's medical during the post-match press conference.
Fans of the Premier League may already be familiar with Manquillo, who spent a large portion of the 2014/15 season on loan at Liverpool. His loan deal there was terminated early however, after the now 22-year-old only featured in three cup matches in 2015 and none at all in the Premier League.
The 2015/16 season saw Manquillo play regular football in Ligue 1 with Olympique Marseille alongside former Sunderland striker Steven Fletcher, with the Spaniard making 31 appearances as the club struggled in the French top-flight.
Imminent signing provides options at full-back
Manquillo has featured for the Spanish national team from the U16's all the way up to the U21 squad, although he has not been able to make his senior debut for his country as of yet.
The imminent signing of Manquillo offers some competition in the full-back area for David Moyes' side, who currently have only two fit full-backs available in Patrick van Aanholt and the recently signed Donald Love, with Billy Jones still out with a hip injury.
If all goes to plan then fans can expect Manquillo to be formally announced as a Sunderland player in the coming days, representing a sign of the progress that Moyes had planned to make in the transfer market before it closes on September 1.
