Actually the own goal, is it robertson fault or van dijk?

From the replay it seems like van dijk try to clear the ball but hit robertson and then went in....and it looks like robertson was shouting at van dijk and ask him to leave it to him or alisson to handle?

But still I think robertson really past his time already....too many mistake this year and didnt contribute much to assists as well.....hope the milos kerkez deal can ON....

looks like another defeat in the making. sigh!
