Gareth Bale has warned Slovakia he is playing with “anger” as his Real Madrid woes continue.
Wales’ record scorer is set to win his 80th cap on Thursday night as he aims to add to his 32 international goals.
But his club future remains frosty in Spain where he has a cool relationship with boss Zinedine Zidane after the Frenchman tried to force him out in the summer.
Bale has since been reintroduced into Real’s side, making seven appearances and scoring twice after a lucrative proposed switch to China collapsed.
He started the La Liga leaders’ last game in a 4-2 win against Granada on Saturday but missed their previous Champions League clash and Bale even refused to hold the Real Madrid pennant in the team picture before their tie at Paris Saint-Germain in September.
Now the attacking ace has admitted he is full of fire when he steps out on to the pitch.
Bale, who turned 30 in July, admitted: “You play with a lot of emotion. Anger comes into it but I am just trying to play football and trying to enjoy it as much as I can to give my best whether I am here or at Madrid.
“When I go on the pitch I try to give 100 per cent as much as I can to help the team and I will continue to do that.”
Bale is understood to be more determined than ever to leave Madrid but club officials have told him to see out the season before reviewing his future next summer.
He will then have just two years left on his mega contract worth over £600,000-a-week.
And he was asked if he had to empty his head when he goes away on international duty – but Bale insisted: “I haven’t got anything to clear my mind about.
“I love meeting up with Wales and everyone knows that. It is something I have always loved doing.
“We have a task at hand to try and qualify for the Euros and it is a massive game for us. We are looking forward to it and want to win the game.”
Wales will be without Juventus star Aaron Ramsey who has been left behind with an abductor muscle problem to focus on his fitness for the visit of Croatia on Sunday.
But Ryan Giggs’ side are still hopeful ahead of the clash in the Anton Malatinsky Stadium in Trnava after beating Slovakia in their previous three meetings.
Bale himself scored his first international goal against Slovakia in October 2006 in a 5-1 home loss.
He also netted a free-kick against Slovakia in Wales’ opening Euro 2016 group game.
Now Bale wants to find the net again as fourth-placed Wales aim to go second in the Group E if Croatia beat Hungary at home.
Bale added: “We want to win the game and get the three points and try and put ourselves back in the mix. We understand the situation in the group. I have scored against Slovakia in the past and I am going to be trying to score again.
“I have played against Slovakia quite a few times and we had some good results, especially of late. It is always a difficult game against them but hopefully we come out with the three points.”
If Wales lose it is likely to end their hopes of automatically reaching Euro 2020 but they could still make it through the Nations League play-offs.
