The Welsh winger was named among the substitutes on Tuesday but his manager talked up his importance to the side
Real Madrid head coach Zinedine Zidane insisted Gareth Bale is a "very important" player for the Spanish and European champions.
Former Tottenham star Bale, who continues to be linked with a return to the Premier League, started on the bench as two-time reigning Champions League winners Madrid advanced to the quarter-finals following Tuesday's 2-1 victory over a 10-man Paris Saint-Germain.
The Wales international forward was introduced with 14 minutes remaining in Paris, where Madrid sealed a 5-2 aggregate triumph.
