The Portuguese superstar was sent off in the first half of Juve’ s 2- 0 win away to Valencia last week after a clash with Jeison Murillo .
He risked a potentially lengthy suspension, but instead the 33-year- old will only sit out his team’ s game at home to Swiss champions Young Boys next week.
Juve then play Jose Mourinho’ s United at Old Trafford on Tuesday, October 23, before hosting the English club in Turin on November 7 in Group H.
Ronaldo, a five – time Champions League winner , first won the competition with United in 2008 before leaving for Real Madrid a year later .
He moved to Juventus in July after nine years in the Spanish capital, and has so far scored three goals in Serie A for his new club .
