1. Weaker teams.
2. Depends on the formations used, but always supported (wingers or AMC or another ST).
3. Much lower value and slow training striker (from last season) scoring more goals than him; also, he seems to have more presence on the pitch.
4. Supported by another ST or not, he does not seem to perform well in terms of scoring goals from open play, especially in important matches.
What is even more annoying is the missed chances, especially in important matches. This is one of the main reasons why I'm considering to sell him.
The only reasons why I have kept him is because of his fast training ability and his attributes profile. But, I'm again considering selling him at the end of the season as performance on the pitch is what matters most. I have to ask others (as a precaution) as they may have come across such a player before where the player is like this the first season and changes after a season, where he turns out to be one of the best players.
