As Chelsea made clear to Ashley Cole he had no future at the club last season, they became linked with a number of left-backs.
While it appears Atletico's Filipe Luis will join, one contender who was strongly touted put on a masterclass at the World Cup yesterday.
That was Switzerland's Ricardo Rodriguez who at only 21, looked every bit the accomplished veteran, and gave no clue that it was his first ever World Cup game. SkySports reported in March that Manchester United were also interested.
Up against Ecuador's experienced winger Antonio Valencia of Manchester United, Rodriguez stood firm, and provided the two assists in Switzerland's 2-1 win.

Rodriguez was solid in defence and cutting in attack, all while racking up a pass completion rate of 91 per cent.
The 21-year-old plays for Bundesliga side Wolfsburg and is coming off the back of a superb season.
His seven goals and 10 assists in all competitions have seen Real Madrid linked along with Chelsea, and with 20 international caps to his name already, he is proving key to Ottmar Hitfeld's squad.
Should Rodriguez maintain his level of performance throughout the World Cup, there is every chance the chase for his signature will heat up, and if Chelsea's deal for Filipe Luis falls through or United's for Luke Shaw, moving for the Swiss sensation would be a very wise move.
