Bale drew a blank again at home to Valencia on Saturday, despite seeing an early effort superbly stopped by Valencia goalkeeper Neto.
However, the Wales star rarely threatened the goal after that and was eventually withdrawn by head coach Santiago Solari in the 63rd minute.
Solari said he hoped to get Bale back to his best after he was confirmed as permanent Real head coach last month so he must be concerned at the 29-year-old’s barren run.
His domestic struggles are in sharp contrast to his form in Europe. Bale’s strike against Roma in the Champions League in midweek means he has now either found the target or laid on an assist in each of his last five European outings, his best run in the competition.
Bale has also scored two goals in four appearances for Wales this campaign, but hasn’t hit the back of the net in La Liga since scoring in a 4-1 win over Leganes in August.
Earlier this week Bale’s agent, Jonathan Barnett, insisted the forward was “very happy at Real Madrid” though stopped short of ruling out a future transfer.
When asked whether Bale could follow former teammate Cristiano Ronaldo to Serie A, Barnett admitted “nothing is impossible”.
Despite Bale’s woes Real Madrid went on to secure victory with an early Daniel Wass own goal added to by Lucas Vazquez's late strike a 2-0 win.
Vazquez has now scored in back-to-back games for Real Madrid in all competitions for just the second time in his career – the first occurring more than two years ago.
Meanwhile Solari must be delighted with the form of striker Karim Benzema, who set up Vazquez for the second goal.
The 30-year-old striker has now been involved in nine goals in his last 10 games in all competitions.
The win lifted Real up to fifth and level on 23 points with fourth-placed Alaves.
