Interesting/useful look at how Vlasic has been this season at the bottom of this article:

Essentially, pretty bloody interesting numbers for a 21 year old in the Champions League against the likes of Real Madrid & Roma - who Everton already own.

Nikola Vlasic
Everton parted with £10 million to sign Nikola Vlasic from Hadjuk Split in the summer of 2017, but he never really got a proper run in the side during his first year in England. He only once started consecutive league matches as part of seven starts and five substitute appearances. Attacking arrivals midway through that season and at the start of the current campaign pushed him further down the pecking order.
So Everton sent him out on loan to CSKA Moscow, where he was a standout performer during the Champions League group stage for a side who somehow contrived to finish bottom of their group despite defeating Real Madrid home and away.
Playing in a variety of positions across the attacking midfield line, he provided a combined 0.24xG + xGA per 90, yielding one non-penalty goal (plus two penalties) and two assists for a scoring contribution of 0.47 per 90. He most impressed with his ability to progress the ball forward on the pass and the dribble. He led his side in successful dribbles and deep progressions, and ranked second in terms of moving the ball into the penalty area.
What he provided to his team sat somewhere between a midfielder.
And an attacking midfielder/winger.
Given the quality of opposition, with Roma and Viktoria Plzen the other two teams in the group, this relatively small sample suggests Everton have a player with a very interesting skillset who is capable of taking on a more central role than the right wing position he was generally assigned last season. Will he get the opportunity to show it?"
