The promising youngster suffered a hamstring injury while playing for England's Under-19 team.
The 18-year old picked up a hamstring strain while on international duty for the England Under-19s last week in the European Under-19 Championship and is set to be out for a month.
Klopp’s anger stems from the fact that Rossiter played three games in five days and the German claimed this was unheard of for a player of his age – as reported by the Guardian.
Danny Murphy – speaking on Colin Murray’s talkSPORT show this morning (aired at 11:20) – sided with the new Liverpool boss and suggested the youngster should have been handled better.
“I think he (Klopp) made a lot of sense. I’m not averse to youngsters playing a lot of games to gain experience but three in five days is a bit excessive, especially when the final one against Italy was a dead rubber – it’s asking for trouble,” said Murphy.
The former pro also felt Rossiter’s style of play means asking him to play that many games in such a short space of time is an even greater risk.
“There’s a difference between asking a centre-half to play three games in five days and a midfielder because of the amount of running and intense work they do.
“Rossiter’s an all-action player who puts himself about and I think Aidy Boothroyd made a big mistake and he’ll probably be getting a grilling from the FA because they don’t need this,” he added.
The argument marks Klopp’s first run-in with the FA since his arrival and with Liverpool’s considerable amount of English talent, it probably won’t be his last.
