Bangar's assessment of Sehwag, who is 36, comes after he observed him at the Kings XI Punjab's training camp in Pune ahead of the IPL opener against Rajasthan Royals on April 10.
"Yes most definitely, he can," Bangar told PTI when asked about Sehwag's return to the national fold. The dashing opener last played for India in March 2013.
"He is very motivated. He is working a lot on his fitness. He had a decent first class season too. We were practising match situations yesterday and he was outstanding in that. As it is we all know, the kind of cricket he can play," said India's assistant coach.
Bangar, who has earned rich praise through his India stint, said everyone in the team including Sehwag will have to play well to figure in the eleven.
"Whether it is Vijay or Viru, there is competition for every slot in our team. Whoever is hitting the ball well under pressure situations, is in peak form and fitness, will get a go," asserted Bangar.
Sehwag looked in good touch in the two recent T20 games he played for Delhi, scoring 85 and 39 against J&K and Punjab respectively.
The core of the squad remains the same with only three players bought at the February auction. Bangar sounded upbeat about the upcoming season before stressing that it was important to build on the positives of last season.
"The good thing is all of our boys have been involved with playing the game at some level. Lots of them have done well in the domestic season, so it augurs well for the team. The Indian fast bowlers look in fine touch especially the likes of Shardul Thakur, Anureet Singh, Sandeep Sharma, Rishi Dhawan," he said.
