Lucao's hat-trick, the 'dog' slur and Hai Phong's tactical voids at Lach Tray

On the night of September 5, at Lach Tray Stadium, Lucas Vinicius, known as Lucao, stood silently in the center circle after the final whistle. He had just scored a hat-trick against his former club Hai Phong, helping Ninh Binh to a 4-1 victory in the opening match of V-League 2026-2027. His celebration was met with anger from a section of Hai Phong fans. A Facebook page named HPFC Capital posted: "Raise a dog to see its loyalty," which sparked widespread controversy. Yet beneath the emotional outburst lies a deeper issue: the tactical voids in Hai Phong's defensive structure. Lucao joined Hai Phong in 2026 and became their main striker. His contract ended after the 2026-2026 season and was not renewed. He moved to The Cong-Viettel. Last season, he scored a brace against Hai Phong at Lach Tray. This season, newly promoted Ninh Binh signed him. In the first round, he scored three goals against his old team. The reaction from some fans was vitriolic, but the real story is not about loyalty—it is about the spaces left by a team that failed to replace its key player. Watching the match footage, all three of Lucao's goals originated from the same area: the gap between Hai Phong's right-back and right-sided center-back. The first goal came in the 23rd minute after a quick transition. The second arrived from a cleared corner, with the defensive midfielder failing to cover. The third was a classic counter-attack in the 74th minute when Hai Phong pushed too high. Ninh Binh exploited these gaps with precision. Lucao's movement was intelligent, but the spaces were generously provided by Hai Phong's disorganized defense. The formula is not found on the tactical board. It lies in the spaces that tactics inadvertently leave behind. Instead of analyzing these failures, a small group of fans resorted to personal insults. But the real target of their anger should be their own club's management. Why did Hai Phong let Lucao go? Why was there no adequate replacement? Why did the defense fail to maintain its shape? These are the questions that matter. Loyalty is not a one-way street. Players, like workers in any profession, have the right to move to better opportunities. Modern football is built on professionalism. When clubs fail to recognize value, they pay the price. Fans must accept that the sport has evolved. The culture of a football club is revealed when all plans fall apart. Hai Phong's plan fell apart, and so did the composure of some supporters. In the future, Vietnamese football will grow faster if everyone—including fans—adopts a more professional mindset. Instead of cursing a player for doing his job, they should question their own team's shortcomings. Lucao did not betray Hai Phong; he simply played the game he is paid to play. The real betrayal would be if Hai Phong's leaders refuse to learn from this tactical lesson.
