Saracens director of rugby Mark McCall has praised Manu Vunipola, with the young fly-half an option to replace the suspended Owen Farrell for the huge European tie at Leinster on Saturday.

England captain Farrell is absent for the Heineken Champions Cup holders after being issued with a five-match ban for a dangerous tackle against Wasps earlier in the month.
