According to the latest results and current form of the teams, the forecast for the match between Viettel and Haiphong suggests low scoring. Both teams have one win each in the last month and show inconsistent play. It is very likely that there will be a lack of goals in this match, considering the poor scoring record of Congan and the potential tension between the opponents aiming to climb the table. Based on these factors, it is recommended to bet on under 2.5 goals in the match between Viettel and Haiphong.
