The trio have joined the Porcupine Warriors and they have formed a strong partnership with the existing players in the team.
Kotoko have been in a remarkable form in the ongoing G-6 Tournament – they have won two games, recording 3-0 win over Bechem United and 2-0 against Wa All Stars.
And Osei has attributed the club’s pre-season form to the arrival of the trio.
“I’m happy with the level of competition in the team, taking into consideration of our two matches I think the boys are doing very well.
“Prince Acquah, Isaac Quansah and Conney Idan are doing very well. They have the quality because last season I was lacking players like them, I think they are helping the team so I’m happy to get them,” Osei told the the media after Kotoko 2-0 win over Wa All Stars on Monday.
Asante Kotoko would have to overcome Hearts of Oak in the weekend if they want to reach the final and defend the G-6 title they won last season.
