Bundesliga player ratings

I was looking for a ‘simple’ way to rate football players with the use of available data. The website Kicker rates all players in the matches in the Bundesliga, 2. Bundesliga and 3. Bundesliga. Currently I have scraped all historic matches of the current players in the three major German leagues. As visualization tool I have chosen Dash, made by Plotly. Currently this app is offline. I will relaunch the app soon as a Bokeh Plots app.
