BARCELONA, Spain -- Fresh off scoring a hat trick, Turkey midfielder Arda Turan is hoping for another chance to prove he can play alongside Barcelonas best.With Neymar suspended for Saturdays Spanish league match at Osasuna, Turan is likely to take his spot next to Lionel Messi and Luis Suarez in the defending champions vaunted attack.Turan filled in superbly for Neymar on Tuesday when he scored his first hat trick for Barcelona to lead the team to a 4-0 victory over Borussia Moenchengladbach in the Champions League.The treble took Turans scoring total for the season to eight goals, making him Barcelonas third-leading scorer behind Messi (20) and Suarez (12).Even though nobody doubts Neymar is the more talented of the two, the Brazil striker has managed only six goals despite playing 400 minutes more than Turan this season.Neymars suspensions from both the `Gladbach and Osasuna matches were for accumulation of bookings in both competitions.Arda is scoring lots of goals. When he plays on the wing he has many skills he can draw on, Barcelona coach Luis Enrique said. He can also play in midfield. I am happy for him.Turan, however, has proven to be a tough piece for Luis Enrique to fit into Barcelonas talent-laden puzzle.As his coach said, Turan has impressed on the left side of the attack. But that spot has Neymars name stamped on it, and Turan has struggled when asked to play further back.While Turan flourishes when given space and the freedom to break down defenses, he looks uncomfortable in Barcelonas demanding precision passing approach.His unease with the defensive tasks that playing in midfield entails was clear in last weekends match against Real Madrid when Turan went on as a late substitute to help protect a one-goal lead.Instead, Turans foul on Marcelo conceded a dangerous free kick that Luka Modric didnt waste, placing a cross for Sergio Ramos to head in a 90th-minute equalizer and snatch a 1-1 draw that kept Madrid six points clear at the top of the Spanish table.Turan took a lot of heat for that foul in the Barcelona sports media, meaning his three goals against `Gladbach couldnt have come at a better time.We havent played well recently and havent gotten good results, Turan said. We tried to get the best possible result and play at our best (against `Gladbach).Now 29, Turan developed into one of the leagues top attacking midfielders through four seasons with Diego Simeone at Atletico Madrid, helping the once second-rate team become one of Europes best with league, Copa del Rey and Europa League titles.But when Barcelona called in 2015, Turan changed clubs despite knowing that he couldnt play until 2016 because of Barcelonas FIFA-imposed one-year ban on new players for breaking its transfer rules regarding underage players.The former Galatasaray standout also joined Barcelona well aware that competition for playing time, never mind a regular starting role, would be fierce with the likes of Messi, Suarez and, above all, Neymar.After failing to find a spot following his debut midway through last campaign, Turan made a promising start to this season when Neymar was away playing for Brazil.He scored twice in a Spanish Super Cup victory over Sevilla and notched Barcelonas first league goal of the season. But once Neymar was back from helping Brazil win the Olympic gold medal, Turan was back on the bench.The reserve role clearly didnt suit him. Only one of his goals this season has come as a substitute, when he sparked a 2-1 comeback at `Gladbach in September.Unlike this weeks second win over `Gladbach, which came with Barcelona already qualified for the Champions Leagues knockout rounds, Barcelona visits Pamplona on Saturday needing to break a run of three straight league draws.Promoted Osasuna appears to be the optimum rival to end that skid.
