Former Arsenal Defender, William Gallas has endorsed manager Mikel Arteta's decision to sign Riccardo Calafiori from Bologna.
Gallas believes the Italian defender would be a good signing for the Premier League North London club.
Calafiori is set to join Artetas side imminently after a breakthrough in negotiations was made earlier this week.
The 22-year-old is set to undergo a medical with the Gunners.
My friend played in Italy for several years and watches Serie A every week - he played for Inter Milan and Lazio, he was a great player, but I'm not going to say who - and he told me that Ricardo Calafiori is really, really good, Gallas told Gambling Zone.
