Southampton are still in talks with Spartak Moscow over a deal to sign winger Quincy Promes, according to Sky sources.
Mauricio Pellegrino has confirmed Southampton are still "pushing" on a deal to bring the Dutch winger to St Mary's in the January transfer window.
Sky Sports News understands Promes is keen on a move to England, but Spartak are holding out for a fee in the region of £30m.
Southampton completed the signing of Guido Carrillo from Monaco on Thursday on a three-and-a-half-year contract, but that deal has not dampened the club's interest in Promes.

Any deal would likely eclipse Southampton's current £18.1m club-record fee paid for midfielder Mario Lemina from Juventus last summer.
Promes has scored 53 goals in 101 Russian Premier League appearances for Spartak after joining them from FC Twente in August 2014 for a reported £12m.
The 26-year-old, who is under contract in Moscow until June 2021, was key in Spartak's league title win last season and was named the Russian Premier League footballer of the year for 2017.
