I didn't believe until the end that Barcelona could beat Osasuna so easily, but it happened and apparently the bookmakers correctly assessed the chances of the teams. Everything was decided in the first half hour of the first half, when Olmo converted a penalty to make the score 2-0 and Osasuna had no chance to win. I thought that at least one goal Osasuna players will be able to score, but it was Barcelona's night in which Flick's team completely dominated the field.
Flick now has a fantastic win rate of 75% just like when Luis Enrique trained Barca, who has now put together a great team in PSG and is on his way to winning the Champions League.
Usually after international break things create chaos because players have unwanted stuff which give them fatigue so many were expecting this game could be tense for Barcelona but Hansi Flick done good work and bring players with good strategy which give them time for having good performance.
In early minutes of the game, having 2 goals give huge boost while Osasuna were not able to set themselves after this aggressive work after losing two games in December against Atlético Madrid and Leganés at home they regroup themselves which increase their confidence. Now they are at the top while things are also favourable for them to keep things on balance and have fair chance of winning title after having poor run-in last season while chances are high for them to complete treble as well.
