F1 drivers are under pressure to perform every time they get behind the wheel of their cars but some are undoubtedly more in need of a strong result than others at this weekend’s Spanish GP. Troy Polamalu Jersey . Amid the backdrop of Max Verstappen and Daniil Kvyat trading Red Bull places, and Nico Rosberg leaving Lewis Hamilton and Sebastian Vettel trailing in the world title battle, we asked some of the Sky Sports F1 team to pick the drivers who they feel are under the most pressure at Barcelona… TED KRAVITZHalf the grid is under severe pressure. From Daniil Kvyat, to show that Red Bull were wrong to drop him. From Jolyon Palmer, to see off the pressure from Esteban Ocon. From Lewis Hamilton, to get his championship going again. And to Sebastian Vettel because Sergio Marchionne, the Ferrari president, says he expects a win here.When is the Spanish GP and how can you watch it on Sky SportsBut the biggest pressure has to be on Max Verstappen. Red Bull have caused the disruption by changing their driver line-up and now they need the justification - and its up to Verstappen to deliver on that. Its his first weekend with a new team and new engineers, so I would say that is the biggest pressure of the weekend right there on his young shoulders. DAVID CROFTThere are 22 drivers under pressure this weekend.You cant say one is under more pressure, really, because of the environment of F1: everybody has to beat their team-mate, to produce the goods, and justify why theyre in that seat.At Renault, Jolyon Palmer is under pressure to have a really good race on a track he knows well. Kevin Magnussen knows it equally as well and can make life difficult for Jolyon.Obviously, Daniil Kvyat will be looking for a good result to boost his confidence and to put it into the back of Helmut Markos mind he could still be the man for the top team. Max Verstappen has also got to deliver now he has been promoted, while Daniel Ricciardo has got a third different team-mate at the senior team so hell be under pressure too to prove he is still the numero uno there.Spanish GP talking points Then theres Lewis Hamilton, who is under pressure because he needs a good result. But hes not driving badly, so hell continue doing what hes been doing.So the man under the most pressure is Nico Rosberg because hes the guy who is leading the championship. He is the hunted, everybody else are the hunters. Hes got a 43-point lead to defend at a race track where hell be confident of a successful weekend.The guy under the most pressure is always the one whos leading the championship - but dont discount the individual pressures that are on the other 21 drivers as well. SIMON LAZENBYIts Daniil Kvyat who is under the most pressure.Altruism and Formula 1 dont often go hand in hand and my impression, in this cut-throat world, is that Max Verstappen wouldnt have lost much sleep over whats gone on - but Kvyat is probably not particularly well rested.Whats different on the cars in BarcelonaHes certainly under pressure now. Hes probably been lying awake at night thinking about his future because hes been put in a very difficult position.Watch the Spanish GP live on Sky Sports F1.

On June 26, FIFA banned Suarez for nine international matches for his bite to the shoulder of Italian defender Giorgio Chiellini during Uruguays June 24 1-0 group stage win over the Azzurri. Additional to the international ban, Suarez was suspended from all footballing activity for four months. The ban effectively prevents Suarez from taking part in the 2015 Copa America in Chile and has derailed, at least for the time, a proposed transfer to Barcelona. This is the fourth major suspension for Suarez, 27,, over the course of his career, having been twice previously suspended for biting an opponent (once at Ajax and once at Liverpool) and once for racially abusing Manchester United defender Patrice Evra. Mike Hilton Jersey. To compensate for Suarezs absence, Liverpool is expected to sign Benfica winger Lazar Markovic and Standard Liege Belgium international forward Divock Origi in the coming days.
