Arsenal boss Arsene Wenger is the man haunting Juventus as they attempt to complete their business in the transfer market.
Despite the Frenchman's admission he may not sign anybody for Arsenal if he does not settle on the right player at the right price, the Italian champions are fearful he could scupper their late targets.
Italian website TuttoJuve write, in an article titled 'Wenger the enemy':
"The Arsenal manager is a major obstacle in the negotiations Bianconeri market. The French coach had already won the race to sign Sanchez.
"This is the first move, the second of Wenger is on Manolas, a defender who Juventus like so much. Arsenal aided by the special relationship with Olympiakos have a clear advantage and will probably end up in London.
They go onto add: "The third and final "insult from the enemy Wenger", he covets Rabiot."
While obviously meant a little tongue-in-cheek, there is a real fear among the Juventus support that they will be beaten to both Manolas and Rabiot by the Gunners.
Just like the situation with Alexis Sanchez, Juventus cannot afford to outbid Arsenal. This is why they have been linked with selling Arturo Vidal to Manchester United, to give the club greater power in the market.
With regard to the special relationship with Olympiakos, it is assumed Juventus are referring to the perceived headstart in negotiations Arsenal may have after loaning Joel Campbell to the Greek side last season.
It is not taken as a given that Arsenal will move for Manolas or Rabiot, but knowing the Gunners are interested could frighten Juventus off, or intensify their pursuit to try and get a headstart on the North London side.
Knowing that the Gunners are looking at the same players interesting the Italian champions, has to be a positive side for fans to take, regarding the club's transfer policy.
