Both of these teams performed very well but the worst for me was Villarreal's failure to control the offside. If they could have controlled the offside, they would not have lost by such a margin, Villarreal had the hardest time in this match. Because even after scoring a few goals, the goals were disallowed only for offside, there was a slight offside like a little bit of a body part. However, Villarreal's players need to gain more experience in order not to make such mistakes in the attacking department, where these small mistakes have led to serious risks.
Because the gamblers who bet on the draw and Villarreal team undoubtedly lost and suffered losses, I thank the Barcelona team players because their offsides were minimal and the goalkeeper's weakness allowed them to score the most goals.
Villarreal's inability to stay onside was a key factor in their loss. The players definitely need more training in that aspect to avoid costly errors in future games. As you said, these small mistakes can lead to serious consequences, as was evident in this match.
Regarding the performance of Barcelona, their minimal offsides indeed played a significant role in securing a lead. Also, exploiting the goalkeeper's weakness added to their advantage. Bettors who had wagered on Villarreal or a draw indeed had to face a loss due to these outcomes.
In football, even the slightest of margins can have a significant impact, and both teams' results were a perfect illustration of this truth.
