Fasten your seatbelts

With the World Cup closing in and the fixtures piling up, for some the international break is the best rest they will get this season. For others, it is already an afterthought as we reach the business end of the season. For fans, it can drag on. Many of Europe's top teams, including Barcelona and Juventus, are facing tough games that threaten to derail their ambitions. 

This Saturday, Europe's big hitters return with four games the keep you glued to your TV. 

In LaLiga, Sevilla-Barcelona

Barcelona will restart their LaLiga campaign at 20:45 away in Seville, with Ernesto Valverde's side facing what could be the biggest threat yet to their unbeaten record. Valverde is not leaving anything to chance, with no players being rested and everyone who is fit in the squad. The squad also received an unexpected visit from anti-doping control during their last training session, to test the eleven who beat Chelsea 3-0. 

It will be a warm up game for the Copa del Rey final, which will be played between the same two sides later in April, but most of the headlines centre on Lionel Messi. 

The Argentine is a doubt for the fixture after he missed both of his national side's games. A loss for Sevilla could leave them outside of the European qualifying spaces. 

In Serie A, Milan-Juventus

Gattuso has stopped the slide in Milan and turned them into a difficult team to beat, but now they face their biggest challenge yet. Not even Juve can match their current form (five wins in five) and it will be full of difficulties for both sides. The 'Old Lady' have a Champions League clash against Real Madrid on Tuesday and will surely have one eye on that, but the race at the top of the table looks like it will go down to the wire. 

Cuadrado and Khedira will return from injury, which will give Allegri some boost, but Mandzukic is out. Chiellini and Alex Sandro are still doubtful. 

Milan are a tough team to break down, and Napoli play earlier in the day, with the potential to put all the pressure on the Italian champions. 

In the Bundesliga, Bayern-Dortmund

The Bundesliga's biggest game, 'der Klassiker'. Bayern can win the title if other results go their way today and Dortmund will be looking to avoid the embarrassment of having it happen against them. 

After Ancelotti's exit, Bayern have rediscovered their powers under Jupp Heynckes and have been untouchable in the league since. They now sit 17 points above second-placed Schalke, who must win against Freiburg to prolong the league for another week. Michy Batshuayi adds another layer of intrigue, scorer of six goals since his move from Chelsea. 

In France, the Coupe de la Ligue final

PSG and Monaco will square in Bordeaux to round off the day. PSG will be looking to get the sour taste out of their mouth after they were uncermoniously dumped out of the Champions League, by winning their second title of the season. They are understandably favourites. 

But Leonardo Jardim's side are not one to be taken lightly. Although they haven't beaten PSG in the last four games, they are unbeaten since January 24th. In addition, Falcao is back to full fitness and he has retained his eye for goal. 

Neymar-less PSG will be counting on Cavani, Mbappe and di Maria to find the net. The Uruguayan striker has terrified Monaco, scoring eight in his last ten against them.
