Cronulla captain Paul Gallen and former NRL coach Brian Smith engage in Twitter battle Sharks captain Paul Gallen wants nothing to do with Brian Smith after being drawn into a nasty Twitter spat with the former NRL coach. UPDATE: SHARKS captain Paul Gallen has declared he wants nothing to do with Brian Smith after being drawn into a nasty Twitter spat with the former NRL coach. In the hours after Gallen was man of the match in a 32-22 upset of competition leader the Roosters, his Twitter account was abuzz with fiery reactions to a sledge from Smith, one of rugby league's most experienced coaches. Smith accused Gallen of avoiding Roosters rival Dylan Napa, after the young forward hit him with a bell-ringer, and his next comment touched on illegal peptides that were allegedly given to Cronulla players. Gallen today declared his father Garry was the author of a string of angry responses on @PaulGallen13. A sizzling first half performance from Cronulla sets up victory against an outgunned Sydney Roosters, despite a late fightback from Trent Robinson's team. "I warned him what it would do but he came down from Queensland for his 59th birthday yesterday, so I let him jump on and he went a bit mad," Gallen told Sky Sports Radio. Gallen, who was rejected as an Eels junior when Smith was in charge of Parramatta,had a blunt message today for the coach who has infamously never won a premiership after overseeing more than 600 NRL games. "I won't be going back and forth with Brian Smith to give his life any significance," Gallen said. He can have his time in the sun for the next 24 hours and that's about all he's good for. I won't be getting involved with him anymore. Paul Gallen makes another hit-up against the Roosters. Obviously he didn't like me at Parramatta when I was a kid. I had a meeting with him about 2003-04 to go back there and (since then) I've had nothing to do with him. I don't know where it's come from but he's entitled to his opinion and I'll just deal with it today as it comes. The exchange ignited when Smith accused Gallen, who ran more than 200m in the game, of dodging Napa. Former NRL coach Brian Smith. Radio broadcaster Triple M tweeted a Gallen post-match quote: "I ran at him (Napa) three times and he got me once, so I'm up!" Smith replied with his @coachbsmithy account: "He ran at him once and got smashed next two times he ran away from him to avoid further embarrassment." A follower then tweeted: "Peptides may increase a lot of things but heart isn't one if them." Smith replied: "What is heart Use all physical resources? peps give unfair advantage in avlbl phys resources used illegally." Shark's Paul Gallen tackled by Rooster's Mitch Aubusson and Daniel Mortimer during the Cronulla Sharks vs Sydney Roosters game at Remondis Stadium, Cronulla. Gallen's account then fired back: "Looking forward to the time I run into u Brian u couldn't play couldn't coach your just a sad..." Smith replied: "Nice to hear from you Paul." Another tweet sent by Gallen's dad also had a shot at Smith: "Smith won an under 23s comp once and been sacked a lot. Guess this is my last time on Twitter. Gallen's account also tweeted a string of angry shots at "keyboard warriors." "Ha ha you people are so sad u have no meaning in life so u follow mine LOOSER (sic)," his timeline ran, by then past midnight. This is Paul's father in response to all of his critics. You are all so great behind your keyboards and that's as tough as you will ever be. The old man had phone we stick up for family so f... all u typewriter terrorist. His (sic) not used to this. Thanks for the supporters. Gr8 win. Shark's Paul Gallen has words with Rooster's Frank-Paul Nuuausala during the Cronulla Sharks vs Sydney Roosters game at Remondis Stadium, Cronulla. A fan tweeted a pointed remark about peptides and the response read: "Man of the match what did you do last night LOSER? Garry Gallen. Full stop the end. Gallen's account updated this morning: "Wow what a response. Thanks for all u supporters have a great day. Smith was infamous for relentlessly sending players text messages during his coaching career, which stalled when he was shown the door by the Roosters at the end of last season. His relationship had by then worn thin with a number of key players, including halfback Mitchell Pearce. Smith has lost four grand finals, most notably with a record-breaking Eels team in 2001, in a 30-24 loss to Newcastle that read 24-0 to the Knights at half-time. He also lost a decider to the Dragons - the club he took to defeats in 1992 and 1993 - with the Roosters in 2010.
