Sevilla sports chief Joaquin Caparros is making Chelsea striker Michy Batshuayi a transfer priority this month.
Mundo Deportivo says Caparros wants to find a new attacking signing this summer and Batshuayi is his top target.
However, Chelsea are stalling negotiations with Sevilla as they consider their own striker options. Any deal will also require Chelsea having to cover a percentage of Batshuayi's salary.
Celta Vigo striker Maxi Gomez and Porto's Vincent Aboubakar are also under consideration by Sevilla.
But no alternative will be sought until Chelsea make a decision about Batshuayi.
