O'Shea claims Ibrahimovic is just one threat posed by a talented Sweden team.
Martin O'Neill's men face Sweden on June 13th at the Stade de France, the scene of their controversial World Cup qualifying play-off defeat to the French in 2009.
While memories of that tie remain painful for O'Shea, who is one of only four members of the current squad to have been involved in that defeat, he insists the team is now focused on getting a result from Monday's opener.
It's highly likely that Ibrahimovic will lead the line for Erik Hamren side, but O'Shea insists the veteran forward, who remains heavily linked with a move to the Premier League with Manchester United, will not be the only threat.
According to the Chronicle, O'Shea said: “When you qualify for a major tournament, you know you are going to be facing quality players and we are preparing already for Sweden,” he said.
“But watching some of the clips, it’s not just the one player we have to watch out for.

“I know one or two of their other players from the Premier League as well and they have some good quality which shines as well from the balls that he [Ibrahimovic] plays into them, so if you are paying too much attention to one player, the other lads get the benefit of that.
“It’s an all-round thing, you have to keep an eye on not just him because he [Ibrahimovic] is given almost a licence to roam wherever he wants."
Following the contest with Sweden, Ireland travel to Bordeaux to take on Belgium on June 18th, before facing Italy in Lille four days later.
