The Yorkshireman has enjoyed a career-best year with the bat but is still awaiting his first hundred on Australian soil.
Root has enjoyed a career-best year with the bat, reeling off 1,630 runs at an average of 62.69 including six centuries.
But after the first two Tests Down Under, and two unconverted fifties, he is still awaiting his first hundred on Australian soil.
Langer admitted Root loomed large over his side’s planning meetings ahead of the Boxing Day Test in Melbourne, given his status as the heartbeat of the batting order.
“He is a brilliant player, no doubt about that, and we spend a lot of our time working out how to get on top of Joe," ele disse.
“That’s not only because he’s such a world-class player, but he’s also the captain of the opposition. It’s always been a philosophy in the Australian cricket team to put as much pressure on the opposition captain as possible.
“Joe Root is tough though, we say he hasn’t necessarily got a really big 100 ainda, but he’s been an excellent player in this series already so we’ll continue to do our homework on him and make sure, or hope, that we can keep having good effects with him.”
Langer also chose to throw his support behind opener Marcus Harris, who is the only Australian player who has yet to chip in to date. With just 38 runs in four innings he is coming under pressure from the experienced Usman Khawaja, but already knows he will be taking the field at the MCG on Boxing Day.
“He’ll play in the Test, no worries about that,” said Langer. “This is his home ground. He’s played a lot at the MCG. He hasn’t made the runs he’d like to so far, but he dominates domestic cricket.
“We like to back our players in where we can. He showed glimpses in Teste de críquete até aqui, and we’re hopeful that he’ll keep kicking on and keep getting better. It’s a tough, tough gig Test cricket.
“But we’re really confident. Marcus has got what it takes to to be a successful Australian opening batsman. What we see in the nets, what we see in domestic cricket all adds up to watch what is potentially a very good Test career. So let’s hope he starts that off again on Boxing Day.”
Capitão Pat Cummins will return after an enforced period of isolation caused him to miss the Adelaide Test, but Scott Boland has been called up as cover.
