Maybe they're still running now, this Liverpool team. Maybe, as the sun rises over Anfield on Thursday morning, there will still be men in red shirts, chasing, harrying, closing down, sprinting away, as if their lives depended on it.
Jurgen Klopp called for bravery, he called for a team that would dare to make history, and he got it. He got a response that swept the best team in Britain off the pitch, that sent Pep Guardiola and Manchester City back along the M62 vanquished, humbled.
Some will say the tie is not over but if Liverpool play like this again, it is.
