Unai Emery is expecting to be aggressive in the transfer market for the rest of this summer.

Arsenal have only signed 18-year-old Gabriel Martinelli.

The club have been linked with Wilfried Zaha, Kieran Tierney, and William Saliba, though only Newcastle, Crystal Palace, and Norwich have spent less money than Arsenal this summer.

The club have also been linked with a loan move for Dani Ceballos. 

“We are being very, very demanding and are first speaking about the possibility to sign very big, very expensive players and the first player in our list is our first target," said Emery.
