Lazio going after Giroud, but only if Mertens goes to Chelsea: the situation

The possibility of the sale of Mertens to Chelsea is in the balance. The Blues have requested Mertens, but Napoli at the moment do not wish to sell. If president De Laurentiis becomes open to a sale it would then trigger a flurry of other moves, including Lazio making a bid for Giroud. Tottenham is also interested in Chelsea's French striker, but Lazio have already reached a deal with Chelsea. However, the entire scenario depends on Mertens being sold to the Premier League.
