Bale, who opened the scoring as Spurs cantered to a 3-0 victory over the Serie A side in the Europa League last-16 first leg, was shown a yellow card for simulation and will miss the return leg at San Siro next week.
But Villas-Boas was glad to see the 23-year-old pick up a booking because the Welshman will sit out next week’s tie rather than risk picking up a suspension for the quarter-finals.
“Gareth will obviously be a great miss,” Villas-Boas said.
“But had we known we’d get this result we would have asked him to get the yellow card to be clean and to be ready for the last eight.
“It’s not finished but we are in a good position.
“Gareth has been influential in consecutive games but hopefully we can make it without him and go through to the last eight.”
