Chelsea are planning for life without Kepa Arrizabalaga.
The Spaniard wants to depart Stamford Bridge this summer after serving as back-up for Edouard Mendy.
Thomas Tuchel needs competition for Mendy and the Daily Mail reported that the Blues were targeting Lazio goalkeeper Thomas Strakosha.
The 27-year-old is out of contract with Lazio at the end of the month.
Fulham have been strongly linked with Strakosha, but their west London rivals are also interested.
