Erling Haaland is the number one transfer target for Manchester United, but another Bundesliga hotshot could be available for the right price this summer window.

After establishing himself as one of the hottest properties in world football - with 49 goals in 51 games for current club Borussia Dortmund - speculation over the future of Haaland has spiralled in the last seven days.

Indeed, after his representatives were spotted in Spain ahead of proposed transfer talks with Barcelona and Real Madrid, super agent Mino Raiola and father Alf Inge Haaland were reported to have held similar discussions at four Premier League clubs - including United.

Manchester Evening News understands that Haaland remains the top target at Old Trafford this summer.

However, with other possible options out there - even in the Bundesliga - the 20-year-old will not come cheaply.

Although he is reported to have a £65million release clause in his Dortmund contract - set to become active next season - financial concerns brought about by the Covid-19 pandemic mean the German side are anticipated to cash in on one of their most-prized assets before then.

A fee upwards of nine-figures has been mooted, with interest from the La Liga giants - as well as Manchester City, Chelsea and Liverpool - almost certain to ramp his market value up even further.

There is no doubt that Haaland remains sought-after property, but as mentioned above, there are some alternative options out there - and not too far away from Dortmund, either.

One of them, Eintracht Frankfurt striker Andre Silva, even has a record comparable to the Norway sensation.

Perhaps even more importantly, too, his agent Jorge Mendes has strong links with United - as he does with clubs across the Premier League in general.

A super agent held in the highest-regard, Mendes was of course responsible for advising Juventus star Cristiano Ronaldo, who moved to United in 2003 and became one of the world's elite players amid a subsequent switch to Madrid, for £80million, in 2009.

Other players in his esteemed Gestifute clientele include City trio Ederson, Ruben Dias and Bernardo Silva, and the majority of the Portuguese contingent at Wolves.

As the likes of Haaland and Bayern Munich goal-getter Robert Lewandowski continue to attract much attention in Germany and across Europe for their exploits in the Bundesliga, Silva too has compiled a staggering goals tally over the course of this season.

Indeed, the Portuguese striker - capped 38 times by his country, scoring 16 times - has inspired Frankfurt to fourth place in Germany's top division as they close in on an unlikely Champions League place for next season.

A bargain deal worth around £3m took him from AC Milan to the Bundesliga last summer.

Silva has already repaid that fee multiple times over, too, scoring 22 goals and laying on five assists despite playing only 25 games throughout the course of the campaign.

That return actually sees him ahead of Haaland (21 goals) in the race for the golden boot, but both strikers remain someway behind Lewandowski, who scored an astonishing 35 goals in 25 games prior to his injury set-back.

Crucially, though, Silva would almost-certainly be available at a fraction of the price of Haaland - or England captain Harry Kane for that matter.

According to renowned football website Transfermarkt, the 25-year-old's current value is £42m, less than half of what the publication are pricing Haaland (£99m) up at.

There are sure to be plenty of twists and turns along the way as world football prepares to sit back and oversee its latest high-profile transfer saga, but United's pursuit of Haaland in particular may just open the door for Mendes and his latest attacking talent to coming knocking.
