With Lionel Messi one goal from equaling Gerd Mueller's all-time record of 85 goals in a calendar year, Barcelona faces a decision on whether or not to rest the Argentine forward for Wednesday's Champions League match against Benfica.

Messi is currently scoring at a rate of two goals per game, so the record could fall at the Camp Nou. But Barcelona coach Tito Vilanova could instead rest Messi with Spanish league matches against Betis and Atletico Madrid coming up.

Barcelona has already advanced from its Champions League group.
