Arsenal are trying to sign some “very big, very expensive players” this summer, says manager Unai Emery.
Several fan groups and bloggers have called for change at the club and Emery said the Gunners are being “very demanding” with their transfer targets.
They have already had bids rejected for Crystal Palace winger Wilfried Zaha and Celtic left-back Kieran Tierney.
“Our target is to achieve three or four players who really improve our team and our squad now,” said Emery.
“We have very good players and very good young players who can progress to take and get big performances with us. Other players can come here to help us.
“We are being very, very demanding and we are first speaking about the possibility to sign very big, very expensive players.”
