Firhan, whose two-year-old child Nur Ayra Delisha died following a seizure last month, is currently in centralised training with the national squad.
And the forward has vowed to do whatever it takes to make the squad of 25 players as a dedication to his daughter.
Although the past one month have been tough on him, he refuses to dwell on his sorrow.
“I’ve got to be strong. Right now, I tell myself that I’m fighting for my late daughter. I will give my all for her. From now on, every success I achieve, I will dedicate it to her.”
However, to be part of the squad, Firhan will have to compete against Tengku Ahmad Tajuddin Tengku Ahmad Jalil, Mohd Haziq Shamsul, Mohd Azrai Aizad Abu Kamal, Faizal Saari, Mohd Nor Firdaus Rosdi, Mohd Shahril Saabah, Nur Rahull Hrshikesa Tatchana Murthy and Mohd Syamil Azim Dzulkafly.
“Nothing is tough. You only need to focus on training and give your best. Yes, the competition among us is immense, but that is what I need right now.
“It will not only improve the quality of my game but also give me the mental strength to succeed,” said the 27-year-old.
“The intensity during training is high as everyone wants to prove to the coach (A. Arul Selvaraj) that they are worthy of a spot.”
Firhan, who has 185 caps, made his debut in the Asian Champions Trophy in Ordos, China in 2012.
He also featured in two World Cups – in The Hague in 2014 and India in 2018 – and was in the team that won the silver medal in the Jakarta Asian Games in 2018.
His last assignment for the country was in last year’s FIH World Series where Malaysia lost 1-0 to Canada in the final.
