dunno about tuz, but my issue with openda is that he's not a natural 9 like vlahovic. current tactics would have comforted randy much better as you can feed him with long balls and since he's a big enough guy and a decent passer he won't have problems holding and distributing the ball. openda is 10 cm shorter than randy, feeding him with long high balls is useless. same with david. but of course tactics can - and should - be adapted, so it's on tudor to make everything click. yildiz is a passer, so is openda, so there's potential
just my uneducated guess: the plan might be to replace vlahovic with kolo muani next summer
