Arsene Wenger is hoping for good news from Jack Wilshere's latest scans after admitting it is vital to learn when he could be back in action.
The Arsenal midfielder has been sidelined all season with an ankle problem and it emerged last week that he had suffered a new stress fracture to put back his return date.
Wenger had initially been optimistic of having Wilshere available again in February, but his comeback is not imminent and there are just three months of the season remaining.
He will get a clearer idea of how long it will take to recover when he visits a specialist in the next few days, and Wenger is looking for a timely boost.
"I hope that we will get good news from him because that is very important for Arsenal," he said.
"This is the stage where the [latest] scan will be vital to decide when he will come back."
Much has been made of the visits to Chelsea's training ground by Russian owner Roman Abramovich this week to cast his eye over Andre Villas-Boas' squad.
Wenger insists he would not be troubled were the Gunners' American majority shareholder Stan Kroenke to show up at London Colney.
"He can turn up any day," the Arsenal boss said.
"He is the president of the club. You cannot forbid him to come to his own training ground, and he is welcome.
"We have nothing to hide here."
