The transfer window has been quite interesting this summer, featuring a lot of high profile deals and mouth-watering figures as clubs go head-to-head in an intense battle for the finest deals in the market.
While the English Premier League clubs took the lead in spending the highest sums, La Liga outfits have also been doing pretty businesses of their own since the transfer window opened this summer.
Real Madrid and Barcelona have always been the front runners when it comes to acquiring the biggest deals in the Spanish top flight for the past few years. However, they have gotten a strong rival this summer, with Atletico Madrid also stepping up, splashing the cash and luring a number of high-profile superstars to the Wanda Metropolitano.
With the La Liga sides having spent huge fees on acquisitions from the market this summer, we take a look at the top 5 most expensive signings in the Spanish top flight during the transfer window:
#5 Clement Lenglet
Catalan giants, FC Barcelona were one of the busiest clubs in the transfer window this summer, luring a number of fantastic superstars to the Nou Camp, including former Sevilla superstar - Clement Lenglet.
Having impressed while representing the Andalusians during the previous campaign, the defender earned a lot of interest from the La Liga champions - who quickly snapped him up in a deal worth £31.7 million this summer.
Lenglet has had a great start to his Barcelona career, producing a couple of brilliant performances and gradually establishing himself in the Catalan capital. In his first official match for the club, the Frenchman won a spectacular trophy as Barcelona defeated his former side, Sevilla 2-1 to claim the Supercoppa de Espana this month.
#4 Thibaut Courtois
After several months of speculations regarding his future at Chelsea, Belgian International, Thibaut Courtois finally departed the Stamford Bridge and completed his long-awaited move to join Real Madrid in the La Liga this summer.
The goalkeeper became one of the most expensive signings in the Spanish top flight during this transfer window, with Los Blancos coughing out up to £35 million to lure him away from the English Premier League.
Following a brilliant campaign in the FIFA World Cup tournament where he claimed the Golden Glove for his spectacular performances, Courtois will now settle down and compete with Keylor Navas for a starting spot in Real Madrid's line-up this season.
#3 Malcolm
In one of the most dramatic transfers in the summer so far, Barcelona hijacked Roma's move for Brazilian superstar, Malcolm - who was on the verge of completing a deal to join the Italian giants this summer.
It initially looked as though the attacker would move to the Stadio Olimpico, with the Seria A outfit expecting his arrival before he made a shocking U-turn at the airport due to a late interference from Barcelona.
The Catalans made the Brazilian superstar one of the most expensive signings in the Spanish top flight this summer, splashing up to £37 million to lure him from Bordeaux. Malcolm has linked up with other recruits including the likes of Arthur Melo and Clement in the Catalan capital this season.
#2 Vinicius Junior
Following the footsteps of his idol Neymar Junior, Brazilian starlet Vinicius departed the Campeonato Brasileiro Série A and completed a dream move to the La Liga where he signed a 6-year-contract with Spanish giants, Real Madrid.
Despite his age, Los Blancos did not hesitate to make the attacker one of the most expensive signings in the Spanish top flight this summer, coughing out a massive £40 million to beat their European rivals to the signing of the youngster.
Vinicius is a highly talented winger with immense skills and a fantastic style of play. After impressing in his debut match with the first team, the 18-year-old will now move to the B side where he will remain till the end of the campaign.
#1 Thomas Lemar
Atletico Madrid have made themselves one of the favorites to win the La Liga title this season, with their incredible acquisitions from the transfer market - which included the capturing of former Monaco superstar, Thomas Lemar.
The Rojiblancos made the attacker the most expensive acquisition in their history as well as the most expensive signing in the Spanish top flight this summer - paying a whopping £63.2 million to convince the Ligue 1 outfit to part ways with their star forward.
Lemar has begun his Atletico career on a brilliant note, helping the Spanish side to claim the UEFA Super Cup recently. He will continue lining up alongside some of his international teammates including Antoine Griezmann and Lucas Hernandez at Wanda Metropolitano this season.
