In addition to being a coach, Fabregas is also a minority shareholder at Como. So, it's normal that he's trying to improve the team personally. I believe the main reason he's retained his position at Como because of his confidence in improving the team. Playing a dual role isn't easy, but Fabregas is willing to take the risk. However, when he coached Barcelona, he was quite good, so competing for a UEL spot next season still makes sense for Fabregas to reach that position.
