Some fans have claimed the 28-year-old is not fit to don the jersey of any team in the Super League after his poor performances in Selangor last season but Ishak said German had looked sharp in training and friendlies.
He said that instead of lamenting about the past, the former Kerala Blasters striker has vowed to shut his critics up by producing some worthy performances for his new club.
“I admit it is going to be challenging for him after last season but I signed him because he impressed us. There was another player on trial but German fulfilled whatever I wanted. He can finish off chances and has looked sharp in training and friendly matches.
“He did tell me he wants to silence the critics and bounce back. Maybe in Selangor, the pressure was just too high.
“With Police, the pressure is not too high.”
Besides German, Ishak also confirmed that the team have signed two Turkmenistan internationals – Serdar Geldiyev and Shohrat Soyunov.
Geldiyev, 32, last played for Turkmenistan club Altyn Asyr in the Yokary League and has won 12 caps with his country. The 1.90m midfielder has not played outside of his country and the Cops will be his first overseas club.
Centreback Soyunov, 28, is also playing outside of Turkmenistan for the first time. He last played for Ahal in the Yokary League.
Ishak is happy with how they have integrated with the team.
“They have looked imposing, and that is what we want from them.
“We had a South Korean with us, but that transfer did not materialise. We are looking for one more foreign player.
The odds are stacked against Police as the team had to face budget cuts and have to work with a mix of professionals and police officers. To further compound matters, the Football Association of Malaysia (FAM) had slapped them with a three-point penalty after they failed to settle the wages owed to players when they were in the Premier League last season.
The Cops are facing a further six-point deduction if they fail to settle the arrears by Feb 28.
However, Ishak said the boys are giving their all in training.
“We will be playing two more friendly matches against Kelantan (today) and Terengganu (Feb 22). The boys know what I want, but these matches will give me an indication of whether they have truly understood what I want.
“Things do look favourable for me. The local professionals and foreigners are gelling well with the officers.
“For the officers, I do not have much problems with their fitness level, but it is their technical ability that I have to work on. I hope they will improve game-by-game.”
