His last outing in a LionsXII jersey ended in disgrace, after he slapped Sarawak forward Muamer Salibasic in the box right in front of the referee's assistant.
He was sent off, and the resultant penalty condemned the Singapore outfit to a 2-1 defeat.
Back from suspension, Shahfiq Ghani will be looking to deliver a sucker punch against the same opponents Wednesday night at the Jalan Besar Stadium in a crucial Malaysia Cup Group D clash.
The loss in Sarawak means the reigning Malaysian Super League (MSL) champions are struggling to make the quarter-finals of the much-cherished Malaysia Cup.
Tomorrow's penultimate group game - the LionsXII finish the group stage with a match at Kedah on Saturday - is a must-win encounter, a fact not lost on Shahfiq.
Speaking to The New Paper on Monday, the 21-year-old said: "I was frustrated and disappointed with my actions because with 11 men, we could have achieved a result at Sarawak.
"It was a morale booster for me to get my first international goal and to help the Under-23s get a win after three Merdeka Cup defeats.
