Denne bloggen er basert på egne oppsummeringer, ideer og tanker, men henter masse bra info fra kilder som har lagt ut gratis innhold på internett. Flere av disse har egne YouTube kanaler som det kan være verdt å abonnere på. Besøk også deres websider og abonner på deres nyheter/innhold!

This blog is based on our own thoughts, summaries, observations and ideas, but includes tons of freely available tennis information on the web. I would highly recommend to subscribe to these channels on YouTube and visit their websites. This web site will hopefully generate traffic to them or membership! Thanks to all listed below – my effort is limitied to pick and show some of the best available on one place – based on my choice alone.
