Liverpool manager Jurgen Klopp was not happy with the "slapstick" 1-0 defeat to Inter Milan which ended their year-long unbeaten home record but accepts it was the one game they could afford to lose. The Reds carried a two-goal advantage from the San Siro into the second leg of their last-16 Champions League tie at Anfield and ended up needing it after Lautaro Martinez's 61st-minute goal had given the visitors a chance of overturning the deficit. However, Alexis Sanchez's red card for a second bookable offence less than two minutes later blew a hole in Inter's hopes and although Liverpool should have put the result beyond doubt as Mohamed Salah twice hit the post in the second half a fourth quarter-final in five seasons was secured. "Big caveats. The art of football is to lose the right games," said Klopp after a first home defeat in 29 matches spanning the course of 366 days also brought to an end a 12-match winning run.
