Chelsea are eyeing Barcelona midfielder Denis Suarez.
Marca says Chelsea and Valencia are chasing Denis' signature ahead of the winter market.
Both Chelsea boss Maurizio Sarri and Valencia coach Marcelino are both fans of the midfielder and eager to offer him an escape route out of the Nou Camp.
Denis has struggled for action at Barca and is expected to push to leave over the New Year.
Now 24, Denis has previous experience in England with Manchester City.
