Aaron has so far dismissed three batsmen in the England's first innings in the fourth Test, pegging them back with two blows on the first day, before taking another wicket on Day 2.Â (Varun Aaron Lifts India on Pacy Pitch)
"There is a clear message (from the team management); I have got to bowl quick and yes shorter spells are better and helpful in that case.
"I have had five stress fractures but I don't hold myself back from bowling quick," Aaron told reporters after a rain-hit second day at Old Trafford.
"When I was operated on one and a half years ago here, my target was to be here on this tour. I had a good support system, the BCCI backed me and I worked at the NCA and at the MRF. I am glad to be here and I had a good match so far. I am feeling good with my bowling too," said Aaron, visibly pleased with his comeback.
Almost two sessions were washed out with only 36 overs possible on Friday as England reached 237 for 6 in reply to India's 152 all out in their first innings.
Talking about theÂ ball that dismissed Moeen Ali, Aaron said,"I had just bowled a bouncer to him and I followed it up with an inswinger."
With Joe Root and Jos Buttler stopping India's charge with a 67-run stand for the seventh wicket, England now lead by 85 runs with three days remaining in the match.
Aaron said the match was still wide open: "The wicket has changed from what we saw in that first hour. I am happy that I got wickets when we needed them but there is still a long way to go in the match. England are ahead obviously but they are not too much ahead and even a 100 run-lead is manageable," Aaron said.
