I thinks its safe to say that Theo won't get used unless we are losing and need another striker on. Its obvious that Sven has realised he has made a mistake by bringing him to the WC, we'll end up playing 4-5-1/4-3-3 with the three upfront consisting of Lampard/Rooney/Gerrard. Leaving no place for Theo.
As for Owen i feel so bad for the man, he's only just recovered from his foot injury and now he's done his anterior cruciate ligament and maybe out until October/November/Xmas. He's had a lot of bad luck of late with injuries, hopefully these injuries aren't a sign of his body breaking down on him because it would be a great shame to the game to lose a player like Owen.
