Liverpool, April 11: Pinto da Costa, the Porto president, has slammed Mohamed Salah's tackle on Danilo Pereira during his side's Champions League loss to Liverpool on Tuesday.
The Egyptian forward appeared to catch the shin of his opponent during the course of the quarter-final clash at Anfield, which the Primeira Liga side went on to lose 2-0.
Da Costa claimed the Portugal international should be grateful not to leave England with a broken leg after the challenge.
"Danilo should thank God because this is a leg-breaker - trying not to kick the ball," he is quoted as saying by ESPN.
"I thank God he does not have a broken leg."
Salah escaped any censure for the tackle and Da Costa said he was disappointed with many of the decisions made by referee Antonio Mateu Lahoz.
"We want equality for everyone - look at Felipe's tackle which brought a yellow and this for which we are lucky Danilo is not en route to hospital," he said.
Nevertheless, Da Costa is confident that his side can still reach the semi-final stage.
"We can score two goals just like we conceded here," he said.
"We continued to chase the goal, we had chances, there was a penalty which was not given for handball - just look - and Felipe was also caught."
Porto will have the chance to overturn the deficit suffered at Anfield when the teams meet again next Wednesday.
