10 best signings of the summer transfer window 

#8 - Nélson Semedo

Semedo vs Sweden - International Friendly

After proving his worth with Portuguese powerhouse Benfica and earning regular call-ups for Portugal's national team, Nélson Semedo has completed his transfer to FC Barcelona for around £27 million.

The 23-year old is a strong tackler, but can also support the attack with his long runs, as highlighted with 6 assists in the Liga Sagres last season. The Catalans were in desperate need for a right back, at the top level, who's got what it takes to fill-in Dani Alves' shoes.
