European rivals have questioned Arsenal's summer market work, it has been claimed.
The Daily Mail says scouts across Europe are said to have been left 'bemused' by three Gunners deals this summer.
Unai Emery has been afforded the freedom to sign a new-look defence in his first transfer window in north London.
And scouts across the continent are surprised by the trio.
It is claimed there are question marks surrounding all three players.
Lucas Torreira and Matteo Guendouzi, who both signed this summer, are said to have earned the approval of scouts.
