But who could catch him?

A few weeks ago, Fernando Alonso had said that "he had the good fortune to be the only rider to be able to choose which team to go." Soon it is consumed divorce with the Prancing Horse. Fernando was promptly replaced by Sebastian Vettel, who was also at loggerheads with the Red Bull. 
And Alonso? Well, Alonso was very easy, but in reality it is not that Spanish has many possibilities. Indeed, in hindsight, it has only one. But first things first. Once "burned" the Ferrari, there are only three other top teams: Red Bull, Mercedes and McLaren. The first is to be excluded a priori. Red Bull, for his choice, he runs and will run only with the drivers of your nursery, as Kvyat, Ricciardo, and the same Vettel. The landing of a pilot stated to the court of Marko and Matenschitz therefore appears unlikely. Then there would be the Mercedes, the strongest team of the moment, and also the club where Alonso would arrive. However, the line up of the Star, for now, is armored. The vertices Mercedes have no intention of changing their formation. Sure, the drivers of the Silver Arrows are often at loggerheads gone, so much so that only Rosberg has signed a new contract (Hamilton is still pending, but will probably remain in Stuttgart). Would remain only the McLaren Honda. Alonso would be a return (runs for the English team in 2007) and the Japanese engineer would be happy to have the twooo time World Champion in the team. the problem is that Fernando would want a winning car right away, while McLaren would need at least a year of "settling". Among other things, the Honda has proposed a three-year contract. Alonso, however, would like to be able to choose whether to stay at the end of the year, and then go in Mercedes Rosberg and Hamilton in case they decide to leave the German team. In these terms become reasonable hypothesis of the sabbatical year. Idea, however, strongly denied dall'asturiano. Finally, last crazy idea: the Lotus, the former Renault (team with which Alonso won two titles). The Enstone team next year will mount the engines Mercedes, and we talk insistently also the return of Flavio Briatore in the Circus, right in Lotus. 
In short, the situation is not simple Alonso and the McLaren Honda seems the only way forward. 
Otherwise, the Spaniard could go to Williams: the team of Groove is in great shape, and Fernando find his former teammate Massa ... Which would be certainly happy!
