Paulo Fonseca said Roma should thank Liverpool target Alisson as he believes Shakhtar Donetsk would be taking a greater advantage into the second leg of their Champions League last-16 tie if it was not for the goalkeeper's "extraordinary" performance.
Ukrainian champions Shakhtar came from behind to overcome Italian visitors Roma 2-1 in Wednesday's opening leg in Kharkiv.
After in-form attacker Cengiz Under put Roma ahead approaching half-time, Facundo Ferreyra dragged Shakhtar level seven minutes after the interval before Manchester City target Fred's stunning free-kick sealed the comeback.
The margin could have been wider but Alisson – who has been heavily linked with Liverpool – thwarted Marlos and Taison during the contest.
