Manchester United's search for a new central defender has led them to scout Bayer Leverkusen linchpin Omer Toprak, but the Daily Star believe there's already stiff competition for the Turkish international's signature.
Toprak is also being monitored by Liverpool & Tottenham Hotspur with a view to a £12 million January offer, which is no surprise given the 25-year-old's form in Leverkusen's particularly impressive start to the season.
Roger Schmidt's side have only lost once in the Bundesliga this season and Toprak's been a huge part of that, but that form combined with a serious lack of top centre-backs across the continent means Leverkusen now have a big fight on their hands to keep a key player beyond next summer.
Toprak subject of triple Premier League tussle
The 25-year-old is a player that's easy to root for after making a remarkable recovery from a go-karting accident in 2009, battling back from severe burns to become earn a move to Leverkusen two years later and establish himself as one of the Bundesliga's most reliable defenders.
Toprak's one of the first names on the team sheet at the BayArena, which meant United scouts were assured of a closer look at the centre-back when they travelled to watch Leverkusen face Zenit St Petersburg in the Champions League last week.

What attributes would Toprak offer for £12m?
United's newest transfer target has deceptive pace, strength and spacial awareness, although Liverpool also want defensive reinforcements and could do with the leadership Toprak would provide in that position.
Tottenham Hotspur can't offer Champions League football but would provide Toprak top billing with a fresh challenge in London, which means a formal offer from Spurs would likely be well received by the player's representatives.
Arsenal look a perfect fit for United's new target
While three leading Premier League giants monitor a potential target's progress closely there's one glaring omission in this transfer tussle in Arsenal.
Gunners boss Arsene Wenger desperately need defensive reinforcements, with Nacho Monreal filling in as an emergency centre-back over the last three weeks.
Laurent Koscielny's niggling Achilles problem has heightened the need for Arsenal to land a safe pair of hands as deputy in a pivotal position, so don't be surprised if Man United have yet another rival for an emerging centre-back before the January transfer window finally opens.
