When Benfica sold 21-year-old goalkeeper Jan Oblak to Atletico Madrid last month, he became the most expensive goalkeeper in La Liga history.
The reigning Primeira Liga champions may have pocketed a tidy €16 million for the Slovenian, but they have left themselves in a much-weakened position at the back.
Anyone who witnessed Benfica's 3-1 Emirates Cup defeat against Valencia this week saw that Artur Moraes is not fit for the job, with the 33-year-old conceding three howlers in the space of 15 minutes. Benfica's only other option, currently, is 36-year-old Paulo Lopes, who appeared in just two games (in all competitions) during the 2013/14 campaign.
There does not seem to be one standout transfer target for Jorge Jesus' side. However, there are lots of keepers who are rumoured to be on their way to the Estadio da Luz.
According to Gavin Berry of the Daily Record, Celtic's Fraser Forster was being linked with Benfica last month.
Elsewhere, in Record (in Portuguese), Greek stopper Orestis Karnezis is also mentioned as a possibility, with former Benfica and Panathinaikos manager Jesualdo Ferreira telling the Portuguese newspaper he has the quality to play for Benfica.
Or perhaps we will see the arrival of Sergio Romero before the summer is out. The 27-year-old Sampdoria keeper was on loan last season with Monaco, where he spent most of his time on the bench. However, Romero shone at the World Cup with Argentina, and it looks like he could be on his way to Benfica.
It's a move that is yet to be confirmed by either player or club, but according to Sport Italia (h/t Forzaitalianfootball.com), Sampdoria sporting director Carlo Osti claimed on July 25 that Romero was on the verge of joining the Portuguese champions.
