Jurgen Klopp was not happy about the lack of handshake from Jordan Henderson

It was a frustrating afternoon for Liverpool.

Liverpool have returned to the top of the Premier League table with their 0-0 draw with Manchester United on Sunday but they will feel like it was two points dropped after several injuries forced the hosts into three first-half substitutions and a change of strategy. Jurgen Klopp admitted after the game that his side wasn't up to scratch at Old Trafford and his frustration was clear to see on several occasions throughout the second half. Reds captain Jordan Henderson felt Klopp's wrath with 20 minutes left to play, when the midfielder was withdrawn so that Xherdan Shaqiri could enter the fray. Henderson appeared to ignore Klopp as he made his way to the bench, instead applauding the travelling support and not even looking at his manager, whose hand was outstretched for a handshake. https://twitter.com/LeighCurtis_NP/status/1099695419939012610 https://twitter.com/DanielGarb/status/1099701026930733057 https://twitter.com/JackSear/status/1099701891041320960 Clearly recognising that he had upset Klopp, Henderson returned to the sideline seconds later and attempted to make amends but the German made his anger known. "You didn't shake my hand!" Klopp said angrily before returning to the technical area to concentrate on the rest of the match. Klopp admitted he was "animated on the touchline" in his post-match interview but insisted he did not want to dwell on the result and was looking forward to the upcoming midweek clash with Watford. "I'm not too much interested in the game now," he said. "I'm thinking about Wednesday."
