Torino president Urbano Cairo admits Chelsea's spending power was too much to resist over Davide Zappacosta's sale.

The fullback joined Chelsea on deadline day.

Cairio reflected: "With a heavy heart, we parted with Marco Benassi and Zappacosta. When it came to Zappacosta, Chelsea made an offer that was simply too good to refuse.

“As for Benassi, it was an issue of the tactical system and what was best for him. Sinisa Mihajlovic called yesterday to thank me for the transfer campaign, now it's up to us to prove on the pitch that we can aim for Europe. We mustn't set limits."
