Smith, too, gave an insight of his prime form during the three warm-up games against New Zealand XI, scoring unbeaten 89 and 91 last week. "There's always good rivalry between us and it's going to be nice for us to see how we're at against the best team in the world", Langer said, reported cricket.com.au.
Langer said it was important to remember that Smith and Warner are "human" as they return to top-flight cricket.
Australia head coach Justin Langer likened Steve Smith to master-blaster Sachin Tendulkar after watching the Sydney-born play an "unbelievable shot" in Brisbane."Last week in Brisbane, (Smith) batted beautifully, he played an unbelievable shot off Nathan Coulter-Nile there - it was like watching Sachin bat. And when it comes to playing India and England, we're just going to have to compete harder and be ready for them", he added.
Aside from the expected questions from the media there was little evidence of any lasting effects of a turbulent 12-month period, punctuated by severe recriminations and introspection throughout Australian professional cricket.
Steve Smith and David Warner will be offered additional emotional support from Cricket Australia as they prepare to make their worldwide return in England.
'It's been hilarious for me because whether on the Anzac Cove or in the lunch room or on the bus playing cards, he's just shadow batting the whole time. "He loves batting - he's shadow batting on the sand, he's shadow batting in the shower - I'm not joking".
Langer said Smith is hitting the ball as clean as hard as he was doing it before the ban. "What's more, that is inauspicious for other teams, they know how great these sides are". Australia are the most successful side, having won in 1987, 1999, 2003, 2007 and 2015.
The Aussies will play a practice game against the West Indies on Wednesday (AEST) as Langer looks to ensure the side is ready to make a push for the World Cup.
Langer asked for patience in terms of expecting the best from Smith and Warner as the World Cup draws nearer. We've shown if we stick to the formula then we'll have some success.
The pair are set to represent Australia although both are barred from leadership positions - Smith, the former Test captain, for another year, and Warner, his ex-deputy, for good.
"But we're really clear on the game plan". When everyone says we've got to start playing like England or start playing like New Zealand or start playing like India, no - we'll keep playing like Australia because we've won four of the past five World Cups and that's something to be proud of.
