If the Benzema deal wasn't dead in the water, it definitely is now after the De Gea debacle.
Cavani is also a non starter. He is PSGs main man, and they have just bought Di Maria to provide him with ammunition.
Players in the rumour mill who are possibilities are Higuain, Kokorin, Yarmalenko, and Pato. Though my guess is, if we are to sign anyone today, it will come from left field as Wenger's signings usually do.
Fingers crossed.
