Team generally looks good, there will always be weaker players when using 15 players. I suggest trying to line your team up with what you predict the scores will be, and go for big points instead of picking players that contradict each other. I.e. your current team has Grealish and Luiz, who contradict O'Connell, Lundstram and Alonso's clean sheet points. Except for a defender's goal which is unlikely, one set of players will make the other set blank. If you think Villa will score against Che - pick Grealish / Luiz and a different defender to Alonso (if you drop the price by 0.4 you can swap Luiz for Saka). Vice-versa if you think Che & Shu will keep clean sheets - is it really work having Grealish if you think Che & Shu will keep clean sheets?
