Any tips on identifying a good player in the market?

[Siddharth Shanker Singh]

I heard a saying that you cannot put a player you just bought straightaway into your starting 11. Cos they will play badly. They need time to adjust. Is it true?
So far, I have tried two players and two players are like that.

Its 50-50 chance...It depends on the player...But do at least Stretching and Match Practice to avoid injuries...

It has been seen that if you put a newly recruited player into a match.directly they get injured...It all about personal belief...

No body here knows anything surely about the game...Nordeus never tells us...All the thing are being said by managers on their personal experience......
