Like today against Frankfurt he often tries to shoot the 2nd ball onto the goal after corners and shows a good shoot technique imo. I'd say he could be easily on ST 68. SA is fine though.
Also we should have a look at AGI and HEA, Tasci is quite agile but not in yellows, on the other hand I see his header higher than current 78. At last passing seems a bit underrated in every parameter, he's a very good build up player.
