Here are the five fast bowlers Gujarat Titans can target in the upcoming IPL auction.#1 Wayne ParnellWayne ParnellParnell is an experienced all-rounder who has performed exceptionally well in T20I cricket this year. He is the third-highest wicket taker for South Africa this calendar year with 16 wickets in 13 T20I matches.He is also handy with the bat and can strike the ball big. Parnell is a rejuvenated player and is an integral part of South Africa in T20 cricket. He has prior IPL experience as well, having played 26 games from 2011 to 2014.Parnell will add experience and quality to Gujarat's pace attack and will be a smart buy for Gujarat Titans.#2 Naveen Ul-HaqNaveen Ul-HaqNaveen is a talented young right-arm fast bowler who plays for Afghanistan. He has picked up 13 wickets in nine matches for Afghanistan in T20I cricket this year.Naveen had an excellent season in the Vitality Blast and was the second-highest wicket taker. He picked up 24 wickets at an economy rate of 7.70 for Leicestershire in the Vitality Blast. Naveen will be able to prosper under the able guidance of coach Ashish Nehra and will be a great buy for the Gujarat Titans#3 Vidhwath KaverappaKaverappa is a young right-arm pacer who has done well this domestic season for Karnataka. He bagged 17 wickets in 13 games for the Gulbarga Mystics in the latest edition of the Maharaja Trophy T20 (formerly known as the Karnataka Premier League).Kaverappa also did well for Karnataka in the recently concluded Syed Mushtaq Ali Trophy, bagging 18 wickets in eight matches at a brilliant economy rate of 6.36. In the Vijay Hazare Trophy, he picked up 16 wickets in eight matches. Kaverappa will be a smart signing for the Gujarat Titans as signing him could open up a slot for foreign players with a different skill set.Indian Domestic Cricket Forum - IDCF@IndianIdcfKarnataka vs Punjab QF : Player of the Match : Vidwath Kaverappa: 10-1-40-4 #crickettwitter #VijayHazareTrophy112Karnataka vs Punjab QF : Player of the Match : Vidwath Kaverappa: 10-1-40-4 👏#crickettwitter #VijayHazareTrophy https://t.co/QzHtDCSwI8#4 Craig OvertonCraig OvertonOverton is a right-arm pacer and is vastly experienced in English county cricket. The tall Englishman bowls accurately and has the ability to swing the ball.

Overton will add variety and depth to Gujarat's pace attack and will be a smart buy for the defending champions.#5 Jaydev UnadkatUnadkat has been in great form for Saurashtra and was the highest wicket taker in this season's Vijay Hazare Trophy. He took 19 wickets in 10 matches at an economy rate of 3.33 and has also bowled 16 maiden overs.

Replacing Ferguson with someone who can partner Mohammed Shami and Alzarri Joseph should be at the top of their priority list. Gujarat Titans will have to utilize their purse wisely and look to fill in other loopholes in the squad.
