According to sources, Amorim aims to have his non-international players back in training by this month, ready to work on their fitness and performance.
He wants each player to reach their personal best fitness levels by mid-July, and those who fail to meet these standards may not be considered for the starting lineup at the beginning of the season.
Amorim is determined to turn the team's fortunes around and has even asked to be informed about each player's summer holiday plans.
A club insider revealed that Amorim is under pressure to deliver results and has made it clear that there will be no excuses tolerated.
He believes that a strong preseason is crucial to the team's success and has told the players that their jobs are on the line, along with his own.
The club is eager to see improvement and is not willing to accept any more disappointing results.
