Speaking to Pointsports shortly after the game, Ousman Faal head coach Big Tree FC said their target was to secure the maximum points coming into the game.
They did not have enough preparation for the competition, because they were late to be aware of it, he said.
The goal they conceded was due to lack of concentration, but he was confident his side will fight back for a winning goal, he said.
According to Faal, the tournament was well organized, and he was satisfied with the level of organisation and hoped the committee will continue the momentum.
Pa Ebrima Secka, head coach Galp FC, said he came all out to win the game, and will go back and prepare better in order to secure the vital three points in their next game or at least collect a point.
Most of his players are school boys, and as such do not have much time together, but will prepare better before their next encounter, he added.
“We will work extra hard to collect the maximum points in our next encounter, because we are behind since the other teams in our group collected points.”
He described his players as ‘good’, and that they will work more on defending, because the goals conceded were due to defensive errors.
“Conceding a late goal is something I don’t want but we lacked enough training”, he added.
He was happy with the organization, he said, and advised his players to be disciplined and avoid clashing with the referee.
