Arsenal fullback Hector Bellerin admits the club has transformed under manager Unai Emery.
Many of Arsene Wenger's coaching staff departed along with the Frenchman and Emery has got off to a mixed start, with Arsenal losing two and winning two of their first four Premier League fixtures.
Bellerin said: "It feels like a new club. We have so many new staff. It's a shame for those who have gone, and I am grateful to them all.
"Some had been at the club for many years. But you can understand why a new person would like to put their own stamp on the club."
