The first leg of our last-16 tie against the Spanish outfit - set for a 20:00 GMT kick-off - will be the very first time United face Betis in competitive action, and our first fixture following the disappointing defeat at Liverpool on Sunday.
Marcus, who has not shied away from his own pain following the loss on Merseyside, is keen to kick on and ensure a positive result, as we chase down further silverware under Erik ten Hag this season.
Speaking exclusively to club media ahead of the clash with Betis, our no.10 acknowledges that Manuel Pellegrini's men will provide a stern test in M16.
