Micah Richards has warned new Aston Villa team-mate Fabian Delph over a possible move to Manchester City.
Inverness have announced the signing of former Aldershot winger Jordan Roberts.
The highly-rated full-back is currently shining on the World Cup stage for Chile, and his efforts are generating mounting transfer speculation.
Arsenal and Liverpool are said to be closely monitoring the 26-year-old as they weigh up the merits of summer approaches.
Isla, though, claims to be settled in Italy, having spent his entire senior career to date with Udinese and Juve.
He insists that he has expressed no desire to move on, with any call on his future now resting with Juventus.
Isla told La Tercera: “I am working hard for both Chile and Juventus. For me it is all good.
“Will I stay at Juventus? I know that the fans support me. I have learned from many players at Juventus and continue to work hard.
“If the coach wants me to return, then I am glad because I want to do my best at the World Cup and then return to Juventus.”
Meanwhile, the agent of ex-Juventus striker David Trezeguet has been talking up a possible return to Turin for the former France international.
The 36-year-old is on the books of Argentine outfit River Plate at present, but Antonio Calidendo claims a return to Italy is an option set to be explored.
He said: “If Juventus are thinking about (Didier) Drogba they could easily have Trezeguet in mind as he would be a good option in attack.
“Wouldn’t it be better to re-sign David? It would be a smart move as he has goals in his blood.
“We are talking about two players who are almost the same age - Drogba is 36 and Trezeguet will be 37 in October.
“It is no secret that David would like to end his career in Italy and at Juventus. That would be his dream.
“A financial agreement would be no problem so I now have to meet with the president of Juventus – we have a good relationship – and I will talk to him about the idea of bringing Trezeguet back.”
