Arsenal striker Olivier Giroud has admitted that Sunday's thrashing at Liverpool left him feeling "ashamed" and he believes changes are needed at the club.

The Frenchman came on as a second-half substitute at Anfield, but was unable to prevent the 4-0 drubbing, which has seen the pressure again rack up on Arsene Wenger .

Giroud, who was linked with a move away from the club this summer but chose to fight for his place, has been talking about the emotional scenes following the Anfield clash.

"I was ashamed when I left the pitch against Liverpool. We have to change something," he told France-based radio station RMC.

"I have decided to stay. It's my choice, even if everyone does not understand it.

"I still want to win the Premier League here."

Giroud comments come amid growing disillusionment from the players at the club, as Wenger's future again comes under spotlight following a poor start to the season which has seen them lose two in a row following their opening day win over Leicester.

Only two new players have arrived at the club this summer in Alexandre Lacazette and Sead Kolasinac, while the future of Alexis Sanchez is still unclear, with Manchester City again moving for the forward ahead of Thursday's deadline.
