SOURCE: Who will take the titles on Sunday night?

Every WWE championship will be put on the line when Night of Champions hits Sky Box Office on Sunday evening. The WWE’s latest big PPV sees the biggest stars in sports entertainment converge on the Wachovia Center in Philadelphia – and you can see all of the action live – and in high definition – on Sky Box Office from 1am (Monday morning).

Ahead of the big event, skysports.com takes a look at the key clashes to consider where they will be won and lost. Who will emerge victorious with the WWE Championship? Which Diva will reign supreme? Will Jeff Hardy finally get his hands on gold? Who will Chris Jericho choose as his partner?

These questions and more will be answered this Sunday, at Night of Champions.

ECW Champion Tommy Dreamer vs. Christian

It is fitting that Philadelphia is the host city for this title fight – the city most inexorably linked with the ECW. In Christian, Tommy Dreamer faces a friend and former champion. Christian earned the right to compete against the ECW Original by defeating Vladimir Kozlov, a result Dreamer had admittedly hoped for.

Having lost Mark Henry, Jack Swagger and Finlay to other WWE brands, Christian is the only man standing in the way of Dreamer retaining his title. The battle between two respected individuals and close companions should not disappoint. Either way, the City of Brotherly Love will end the night by crowning a multiple-time champion.
