Jurgen Klopp was mainly relieved none of his Liverpool players picked up injuries on Thursday night.
The Reds played out a 0-0 draw in their final Europa League group fixture with FC Sion on a semi-frozen pitch in Switzerland which could have seen one or two of his players sustain problems.
However, the Liverpool squad got through unscathed leaving Klopp content with the result which sees the Anfield club finish top of Group B with two wins and four draws.
"It was difficult; the ground was very difficult to play and for both teams the first thing to do was show you were prepared for a game like this and that is what my team did," he said.
"It was not our best football and although it is an outdoor sport frozen ground is for other sports.
"Of course in each tournament at this level there should be heating for the ground - that is not good [there was none] - but now we have played here and if we come here again it will maybe be April and I hope it will not be that cold.
"We saw the pitch and we knew what can happen on a pitch like this but as a professional footballer and especially as a manager you cannot talk about the pitch.
"You have to ignore it, try to take it and use it and the only thing that helps in a situation like this is concentration: if you are really ready and prepared and concentrated then usually nothing happens.
"I am really satisfied, no-one is injured and they were very focused and concentrated on the game."
