​PREVIEW: Barcelona look to extend their perfect start to the season against hosts Levante.Barcelona have started LaLiga perfectly this season with four wins from four so far this season. They look to extend this winning run to five against Levante who are unbeaten in the last three.Barcelona have scored 17 goals in the league and 22 in all competitions. They are averaging 4.25 goals per game in LaLiga with Raphinha topping the scoring charts. Barcelona have not just been a phenomenal attacking outfit but also strong in defence, so far they have conceded just two goals and managed three clean sheets, the most of any team in LaLiga.As for Levante, they started the season quite shaky with back-to-back defeats and no goals scored. However, since then they have found some form and taken five points from their last three games. Goalscoring has proved difficult for The Frogs, having only scored in a single game. Levante put up some what of a statement victory in their only home game this season with a 5-2 victory over Real Betis, who have since defeated Real Madrid.Mathew Ryan has been Levante’s key man so far this season and played a pivotal role in their ‘great escape’ from relegation last season. He has the most saves per match by any goalkeeper in LaLiga with 4.4. He will be vital in keeping the Barcelona attack quietIn previous seasons the fixture has always provided goals. The last three times Levante have hosted Barcelona the scoreline have read, 2-3 with a late Barcelona winner, 2-3 with another late Barcelona winner, and 3-3 with a late Levante leveller.Despite this Barcelona come in clear favourites with no new injury concerns and Eric Garcia returning from suspension. Barca are not conceding goals and certainly know where the net is. They control the ball and take the game to the opposition. They have creative outlets who are not afraid to take players on such as new signing Anthony Gordon who has notched up 4 assists thus far and young star Lamine Yamal who shined again midweek in the Champions League against Feyenoord with a goal and two assists.Barcelona manager Hansi Flick has previewed his sides trip to Valencia to face Levante in the media this week and praised their recent performances in particular their win against Real Betis.Flick explained: ‘Levante is a team that played a great match against Betis. They are well-structured. They know how to play in attack, and it will be a good match to compete in’Flick also had great praise for his sides defensive performances despite their attack taking much of the headlines recently.Flick said: ‘We talk a lot about the attack, because they score a lot of goal, but for me, the defence is very important, and I see that everyone is performing at a fantastic level’Flick outlined Barcelona’s priorities for this season following their success in LaLiga last season winning the title by eight points and winning back-to-back titles.He stated: ‘This year we want to win the Champions Lea
