Madrid could target Milik, Hector, Gomes or Perisic following Euro 2016
International tournaments often produce a few big-money moves involving players who make their mark on the biggest stage.
With the Euros now entering the business end, clubs will be starting to target reinforcements. Real Madrid will be watching developments closely, even if president Florentino Perez has a transfer ban hanging over his head, which if enforced will prevent new players arriving at the Bernabeu for the entirety of 2017.
Real hardly require a huge overhaul, and while the rumour mill will grind out star names throughout the summer, coach Zinedine Zidane only really needs to sort the wheat from the chaff in the usual names on his team sheet.
But Madrid have form for landing players who impressed at major tournaments. For instance, James Rodriguez moved to the Bernabeu following his exploits with Colombia at the 2014 World Cup.
Here are a few names Madrid could target if these players continue to impress in France ...
Arkadiusz Milik (Poland and Ajax)
Robert Lewandowski has been heavily linked with a move to the Bernabeu in recent months, but in France the Bayern striker has been completely overshadowed by his 22-year-old strike partner. Milik hit the net in the opening win against Northern Ireland and provided the assist for Jakub Blaszczykowski's strike against Ukraine.
In any case, the pursuit of Lewandowski is a fanciful idea whose popularity is driven by the Spanish sports dailies. Bayern have said he is not for sale and Real buying him could mean au revoir to Karim Benzema, who is favoured by both Zidane and Perez. Real need a backup to the Frenchman, who has rarely faced significant competition at the Bernabeu.
Alvaro Morata is likely to be sold to the highest bidder, and Jese seems unlikely to deliver on his early promise. Milik, meanwhile, has banged in 32 goals in 52 Eredivisie games for Ajax in two seasons.
Jonas Hector (Germany and Cologne)
Left-back Hector broke into Joachim Low's side in November 2014 against Gibraltar and has since amassed 17 caps, one goal and three assists for the world champions. Erik Durm made his debut a few months earlier, was taken to Brazil, never got off the bench and played his penultimate match under Low in November 2014 -- against Gibraltar. Hector replaced him that day and has now done so entirely in the Germany side.
Real have long needed someone to provide a bit of competition for Marcelo, but Hector would be a valuable squad addition in other areas as well. The 26-year-old can operate on the left of midfield, at centre-back and even in the holding role. Twenty-six years old and an undisputed starter for Germany, Hector could be tempted by the lure of European football at club level. Real will re-inherit Fabio Coentrao this summer after his loan at Monaco, but Hector represents a far more resilient and versatile option.
Andre Gomes (Portugal and Valencia)
Gomes' star has been rising steadily since his initial loan move to Valencia from Benfica in July 2014. The central midfielder, who can play on the left and as a winger, made his Portugal debut a couple of months later under Paulo Bento and has established himself this year with Fernando Santos at the helm. In Portugal's opening match in France, he provided the assist for Nani's goal in a 1-1 draw against Iceland and starred in the subsequent shut-out against Austria.
Cast in the creative midfield role in France, Gomes has been one of few Portugal players to try to create some order out of the chaos in Santos' side. Neat in possession, with excellent passing skills and a willingness to get stuck in on the back foot, Gomes could be an interesting addition to Real's midfield, particularly with question marks about Toni Kroos' future at the Bernabeu.
Gomes, 22, has plenty of Liga experience and looks like a star in the making. He has stood out in a much-vaunted Portugal midfield and restricted Renato Sanches, Bayern Munich's €35 million purchase, to the bench. Manchester United and Chelsea have been also been said to have an interest in Gomes, who seems likely to leave Mestalla this summer for the right price.
Ivan Perisic (Croatia and Inter Milan)
There hasn't been a huge amount of Euro fever in Spain's capital thus far. Fans logically see the group stages of a tournament they won in 2008 and 2012 as a bit of a preamble. That's probably fair enough, with their pedigree and wealth of talent. It's also why there was a genuine sense of stunned disbelief when Croatia beat them 2-1 -- the first Spanish defeat at a Euros since 2004.
After the loss, Vicente del Bosque, with a disconsolate air, said: "We knew about Perisic. He is a great player and these things happen in football."
They certainly do happen when Perisic is about. The game was meandering to a conclusion that suited Spain, but the Inter midfielder had different ideas and embarked on a lung-bursting run, leaving Gerard Pique in his wake before hammering a shot past David De Gea at the near post.
Perisic has bagged two goals and an assist at the Euros so far, and with Croatia in the softer half of the draw, Ante Cacic's side are now among the favourites to win the tournament.
Perez may not have been very aware of Perisic's existence before the tournament, but he should have noticed by now. If Croatia are to go deep into the knockout stages, Perisic will be centre stage.
