Bale was Real Madrid's standout performer in their 2-2 draw with Villarreal, scoring once and constantly creating havoc down that left wing.
In fact, since he failed to make an appearance in the Champions League semi-final victory over Bayern Munich, Bale has given a five-goal return on his last four league appearances, including one in the 'Clasico' against Barcelona.
His scintillating form of late presents Zidane with a conundrum ahead of their European final against Liverpool on May 26: to play or not play Bale?
Toni Kroos, Luka Modric and Casemiro seem a fixed presence in midfield and will offer much needed control against the 'Reds' lively front three.
However, Madrid have numerous great attacking threats at their disposal and not enough spaces to include them all.
Whichever way the selection goes, Cristiano Ronaldo will be spearheading the offense but Zidane must choose who will partner him out of: Marco Asensio, Lucas Vazquez, Karim Benzema, Isco and Bale.
Asensio and Vazquez have done a fabulous job in the earlier stages but the Frenchman may turn his hand to experience given that Madrid are defending their European crown for the third year in a row.
His lineup against Villarreal could therefore indicate the direction he is leaning in (Isco, Ronaldo and Bale) but time is running for Zidane. With just six days to go, he must decide who will lead his attack, and soon.
