KUALA LUMPUR: Selangor's Jekyll and Hyde game is starting to worry head coach Tan Cheng Hoe.
The Red Giants suffered a 2-1 loss to Police in the second leg of the Malaysia Cup round of 16 at the Petaling Jaya Stadium last Saturday. Despite the loss, Selangor advanced to the quarter-finals 5-3 on aggregate, and will meet Terengganu next month.
It was only five days earlier that Cheng Hoe praised his men for their "best performance of the season" after beating Negri Sembilan 4-0 in the Super League.
Cheng Hoe said Selangor's inconsistency could affect their hopes of finishing second in the Super League and qualify for the AFC Champions League 2 next year.
The 33-time Malaysia Cup winners are currently second in the 14-team standings with 46 points from 21 matches, and are under pressure from third-placed Kedah who have 40 points from 19 matches.
"The players were complacent with the 4-1 win in the first leg, they didn't play their best. This mentality must change, we cannot be yo-yo," said Cheng Hoe.
"When you take it easy and concede goals, you are under more pressure to bounce back. We must change if we want to move to the next level. The performance from the players must be consistent even under pressure.
"We have ambition to play in Asia, so the players must change their mindset."
The Red Giants will take on Kelantan in the Super League at Sultan Muhammad IV Stadium on Friday.
Kelantan suffered a 10-0 loss to Johor Darul Ta'zim in the second leg of the Malaysia Cup round of 16 match last week.
"Kelantan are a team who have nothing to lose. They beat Negri in the Super League before their big defeat to JDT. We cannot take them lightly," said Cheng Hoe.
