A come-from-behind 2-1 win over Johor FC in a Super League match saw Sarawak give themselves the perfect boost for the tough first-round FA Cup match against Kelantan at the Sultan Mohd IV Stadium in Kota Baru tomorrow.
Sarawak, playing in the Super League after a five-year absence, are feeling the heat but have done well against experienced teams to be placed in mid-table.
Tuesday's win over fancied Johor FC at the Pasir Gudang Stadium had coach Robert Alberts wearing a broad grin.
"It is the perfect boost for the FA Cup match against Kelantan," he said.
The Dutchman added: "Kelantan is the toughest place to play football in Malaysia. But we are going there with confidence.
"We can beat any team on our day ... but we can also lose. That's football."
Sarawak showed character to score through Cameroonian midfielder Guy Bwele, who also wore the skipper's armband for the night, off a free kick in the 34th minute.
Former Johor FC player Azizan Baba headed the winner in the 74th minute from a corner-kick taken by Ashri Chuchu.
Johor FC had earlier taken the lead in the 21st minute through Brazilian signing Arthuro Henrique who curled a left-footed free kick past Sarawak keeper Sani Anuar Kamsani.
The defeat left Johor FC winless at home after four matches.
Sarawak are currently eighth with 11 points after eight matches while Johor FC slipped to ninth with 10 points.
Roberts is also hoping that skipper Hairol Mokhtar could join the team for the Kelantan match.
Hairol did not play against Johor FC as he was allowed to stay back in Kuching to be with his pregnant wife who is in hospital.
