He has played 10 games for us and has 2 assists. Extrapolate that over a season and you have 9 assists, assuming he doesn't get any better, nor worse. He has a pass completion rate of 80%. So he gives the ball away about 20% of the time. A better pass completion rate than Ryan Giles at 79%. Admittedly he has a goals conceded stat much worse than Giles, but then so does McNair and Fry this season, compared with last season.
And all this whilst having the worst start to the season that we have had for decades.
Engel is not a really poor player and it is very easy to prove this wrong. He contributes positively in most of the games he has played in.
