Emotions were certainly running high throughout Sunday's Clasico at the Bernabeu.As with any fierce rivalry, Real Madrid and Barcelona's stars were desperate to get one over each other and yet it looked destined to be a draw when James Rodriguez scored a late equaliser for Zinedine Zidane's ten men.But after being kicked around and even elbowed during the 90 minutes, Lionel Messi popped up with an incredible winner to lift Barca back to the top of La Liga.There had been intense battles going on up and down the pitch throughout the engrossing encounter but things did eventually threaten to boil over after the final whistle.No stranger to controversy, Luis Suarez was involved in a heated altercation with Madrid defender Dani Carvajal.As you can see in the video below, the pair were seen arguing during the game but if you skip to 0:16, you'll see things got a little out of hand later on.The pair start squaring up to each other and the Spanish right-back even grabs Suarez's shirt.Luckily, Ivan Rakitic was able to intervene before it got really serious and separates the duo.

You might also notice Carvajal points to the ground at the very start of the clip and Marca have revealed exactly what he said to provoke Suarez's angry reaction.

"This is the home of the champions," Carvajal said, according to the Spanish publication. "Off to rest, to the Copa del Rey."

Carvajal might be feeling confident his side will win the league but there's no doubt Barca's Clasico win has shifted momentum in their favour.

Los Blancos are level on points with Luis Enrique's side at the top and do still have a game in hand.

However, should they drop points, Barcelona hold the head-to-head advantage which could prove crucial at the end of the season.
