Khawaja, who has not found a place in Australia's 15-man squad for the Champions Trophy, has spoken of his frustration at missing the ODIs in New Zealand.
"Maybe when I younger I would have been frustrated [at missing out on the Tests in India]," Khawaja told foxsports.com.au. "In saying that obviously I would have loved to play in that Test series, [and] when I didn't get to play in that first Test I was a bit frustrated.
"I sort of had an idea I was not going to play in that first Test after I didn't get a run during the tour match. We played brilliant in that first Test match and we won. I was frustrated at the time, not so much because I didn't play in that Test match -- I understand the selectors, Boof [coach Darren Lehmann] and picking the best team and what was going on and I just want Australia to win.
"The most frustrating thing for me was not to play those three ODIs in New Zealand. Getting pulled out from them to come to Dubai to prepare for 10 days and then not play the first Test. So I actually miss out on the one-day matches for Australia. For me that was the tough part.
