The Reds left-back started and provided an assist for Mohamed Salah as Liverpool secured an important three points at Anfield.
But speaking after the game, Tsimikas made clear that not all of his thoughts were on the football, with the Greek international dedicating the win to the people of his homeland.
Three days of national mourning have been declared across the country following the incident, in which a passenger service crashed head on into a freight train.
43 people were killed, with many of the 350 passengers on board students. Protests have since erupted in Greece over the crash, with many seeing it as an accident that had been waiting to happen.
In an interview with LFCTV after the game, Tsimikas, who wore a black armband during the match in memory of those who have died, said:
I want to say, I give this win to my people back in Greece.
We had an accident yesterday, a train crash. May God give power to their families and may they rest in peace.
It was very, very difficult for my people.
Most of them were students who went back to see their families.
I always look forward to seeing my family again because I also live far away.
That is the most important thing in life. To be healthy, and do what you really love.
Tsimikas also passed on his condolences to the people of Greece in an Instagram post after match.
