Szoboszlai's free-kick in the first half put Liverpool ahead but the points would be shared after Richarlison struck in the 90th minute.
“Yeah, it is (a huge disappointment),” Szoboszlai told Sky Sports post-match. “I don’t know (what happened with the performance), to be honest, really nothing to say.
“Again in the last minute, I don’t know how many times it happened in the season already. Really, I don’t know what to say. We have to wake up.”
He continued: “I think in the first half we played very well. We controlled the whole game, I guess they hardly created any chance, maybe they had one or two headers.
“But I think we were under control. But second half, it seems we go out and I don’t know, we just don’t do the same things like in the first half. The question is, why?
“But probably we’ll sit down together and this is the most difficult time, but we have to stick together.”
