Albert Riera has hailed Liverpool's "unbelievable" spirit after their latest comeback triumph against Wigan.

"We just don't know when we are beaten, and that is a quality that was apparent to me the moment I arrived here," Riera told the club's website.

"It really is unbelievable. You get confidence from winning games. It demonstrates how good we are at reacting to adversity. That is so important and is the message that comes across loud and clear."
