Chelsea have previously raided the Seagulls for some of their star talent, including the likes of Moises Caicedo, Marc Cucurella, Rob Sanchez and even their manager Graham Potter.
Huge sums have been spent to varying degrees of success but Chelsea, who are ninth in the Premier League table, are now keen to add to a striker to their ranks.
Last week they were linked with Albion teenager Evan Ferguson – which seems unlikely – but today it appears former Albion and Coventry man Viktor Gyokeres is now their focus.
The 25-year-old Sweden international had three seasons at Brighton but was rarely given a chance to shine in the first team. He had loans at Swansea and Coventry - before joining the Sky Blues on a permanent deal.
He scored 24 goals for Coventry in the Championship and sealed his £20m summer move to Sporting Lisbon, where the goals have continued to flow.
He has 16 in 23 outings for the Portuguese giants, enough to make Chelsea reportedly bid £73m which was rejected.
