The transfer window has been open in European major leagues. So far, Italian Serie A has attracted some big senior names as usual  while Spanish La Liga remains interesting for the players in their peak years like Rodrigo de Paul and Memphis Depay.

This week, two names from English Premier League, the Frenchman Olivier Giroud has finally signed a contract with AC Milan which makes their return to Champions League next season. The former Arsenal man agreed with the two-year deal for € 1 million Euro with the option of one year extension should his performance meet the expectation. The 34-year old striker has won all continental titles with Chelsea and is set to replace Mario Madzukic who is no longer apart from the squad. He could even seal one spot in the line up for certain formation to accompany Zlatan Ibrahimovic upfront.

Another senior figure to join Serie A side is the Portuguese international goalie, Rui Patricio, decided to leave Wolves to sign for AS Roma. Playing under Jose Mourinho is one main reason of his move apart from joining the more elite club than Wolverhampton who has been left by their notable manager Nuno Santo. The 33-year old goalkeeper helped Wolves compete in the Premier League top ten and finish on the 7th in 2019 plus reach quarter final of Europa League 2020. Giallorossi has spent €11.50 million to sign Patricio and loaned out Pau Lopez to Marseille. He is expected to be the number one figure between the sticks.

Apart from them, there are two other notable names to choose to set their next adventure in Serie A, Argentina's Nicola Gonzalez and Brasil winger Felipe Anderson. The former is Argentina international who was apart from Albiceleste squd while winning Copa America earlier this month whereas the latter is a talented winger from West Ham who also spent a year on loan in Porto. The versatile Nico Gonzalez has agreed to join Fiorentina while Anderson is set to return to his former side, Lazio, which is now under Maurizio Sarri.

Meanwhile, La Liga remains the top competition for the players in his peak years. Another Copa America winger, Rodrigo de Paul, opts for Atletico Madrid instead of joining Juventus or Leeds United. Los Rojiblancos paid €40 million for the Argentine who actually has tasted the Spanish top tier in 2014/15 season when he signed for Valencia under Nuno Santo. Unfortunately, he was loaned out in 2016 to his former team, Racing Club before joining Udinese in 2016/17. The 27-year old midfielder is considered fit for Diego Simeone's side in 3-4-2-1 or 4-4-2 formation as the anchorman.

The reigning La Liga champions will have to be cautious next season as the duo Barcelona and Madrid have been revamping the squad. The Catalan side has made four important signings, Memphis Depay, Sergio Aguero, Eric Garcia and Emerson Royal, plus reached agreement to keep hold of Messi. Among those four names, the Dutchman Depay is the one who has become the main man in their transfer window. He gets a chance to prove to the world once again that he deserves to be one of the best forwards in Europe after his initial failure in Manchester United but successful spell in Lyon. In the meantime, Barcelona's archrival, Real Madrid, chose to sign a new manager at the helm, the former Zidane's boss, Carlo Ancelotti, and one of the most notable versatile defender-midfielder in Europe, David Alaba. The Austrian skipper is set to replace Sergio Ramos who refused to sign a new contract and moved to PSG.
