The Ireland boss has stressed the importance of the injured Villa centre back ahead of Poland friendly as crucial World Cup qualifiers loom
The Aston Villa centre back has been out of action for seven months after sustaining an injury at Euro 2012 and has subsequently struggled to regain fitness after undergoing a series of operations.
Trapattoni had placed the 33-year-old on stand-by for the international friendly against Poland on February 6, but has revealed that he has told the defender to concentrate on accelerating his recovery.
"I spoke with him and I said 'okay. He wants to come back, he wants to be here', but I said to him that at this moment, I don't want to make trouble with the club," Trapattoni told reporters.
"We need him for the [World Cup qualifying] matches and it will be important that he gets through these medical tests. I hope he can be ready for the matches."
Meanwhile, the Italian tactician has also expressed his desire to see Derby County trio Conor Sammon, Richard Keogh and Jeff Hendrick in action, after including them in his squad for the first time.
"They have good quality to come into our team and I am very, very anxious to see them," he said. "It will be important.
"They can give us their enthusiasm and commitment and their technical quality, I am sure they can play well," added the Ireland boss.
