Real Madrid summer transfer wishlist: Romelu Lukaku and Harry Kane on Zinedine Zidane's radar

Real Madrid have included Tottenham Hotspur star Harry Kane and Everton's Romelu Lukaku in a shortlist of five strikers wanted to bolster Los Blancos's attack ahead of next season, according to AS. The Spanish publication claims that Real had originally identified Robert Lewandowski as their top priority. However, with Bayern Munich unlikely to negotiate his departure they have drawn a list of alternatives that also includes Borussia's Dortmund Pierre-Emerick Aubameyang and former academy star Alvaro Morata.

Los Blancos have reportedly earmarked the signing of a new number nine as a key part of their expected summer overhaul. Manager Zinedine Zidane has recently been forced to use academy starlet Borja Mayoral to cope with Karim Benzema's injuries, with the controversial French attacker the only current first-team specialist in the role. Here are the strikers Zidane is reportedly considering:

Robert Lewandowski

The Bayern Munich star emerged as a candidate to become the latest Galactico in December last year, when Spanish newspaper AS spotted the player's agent at the Santiago Bernabeu during their win over Getafe. Lewandowski issued no denials at the time, but AS later revealed Real Madrid had been forced to cool their interest following Carlo Ancelotti's appointment as new manager – as the Italian specifically requested that the Bayern board keep the striker in their ranks as a condition of joining the club.

Pierre-Emerick Aubameyang

Lewandowski's fellow Bundelisga star has been heavily linked with a Real Madrid move in recent weeks, with both AS and German newspaper Express reporting he has a pre-agreement to make the switch. The striker himself later claimed that although an agreement is yet to be signed he would love to play for Los Blancos. However, Real Madrid are considering other alternatives as they will face stiff competition from Premier League outfits to sign him.

Alvaro Morata

Real Madrid have an option to buy Morato back from Juventus by paying €30m (£23.7m, $33.6m). The Spaniard is the supporters' choice for the attacking spot, according to a poll recently conducted by AS. However, club officials plan to get him back just so they can sell him elsewhere for a profit, funding the purchase of another Galactico. AS claims Arsenal are his most likely destination, ahead of Liverpool and Bayern Munich.

Romelu Lukaku

AS says Real Madrid previously tried to sign the Belgium international in the 2012/13 season, and he has stormed back onto their radar following a sensational campaign at Goodison Park. However, The Sun has suggested Manchester United are very keen on Lukaku's signing.

Harry Kane

The Spurs striker also appears on Real Madrid's wishlist after his latest brace against Bournemouth, which saw him move ahead of Jamie Vardy as the Premier League top scorer. Los Blancos lured Luka Modric and Gareth Bale from White Hart Lane in recent seasons and may be tempted to once again turn their attention to North London to strengthen their ranks.
