Joselu's statistics are bad for Real Madrid. It is very normal to have a substitute player with this statistic.
My guess is that Real Madrid will transfer Kylian Mbappé as a striker. If Kylian Mbappé comes to this team, it would be very good for both Real Madrid and Kylian Mbappé.
Carlo Ancelotti will never returned back to base because he has huge tasks to complete this season, always concentrated on improving the performance of the club. It's not easy but he just have to do it since he's the main man for the job. Joselu often struggle to match up the expectations he's having in Real Madrid this season. He's in elite team and he should try his possible best to always deliver when the team needs him, he shouldn't relent because a single pull back can ruined his chances of meeting the best XI this season.
