Benfica could be about to upset many of the Premier League's leading sides, with rumours suggesting that the Portuguese outfit are interested in signing Ukraine winger Yevhen Konoplyanka.
According to reports in Portugal cited by talkSPORT, Benfica are keen on a move for the Dnipro wideman and have already contacted the club about the possibility of acquiring the 24-year-old when the transfer window re-opens for business in the new year.
Such news would presumably come as somewhat of a blow to Manchester United, Arsenal, Chelsea and Tottenham with that quartet - along with Liverpool - all having been linked with Konoplyanka's signature in recent weeks, as well as the likes of Bayer Leverkusen and wealthy French champions Paris Saint-Germain.
The fight to sign Konoplyanka - who has impressed on the international stage with eight goals in 35 appearances for Mykhaylo Fomenko's men - looks as if it could be shaping up into one of January's most intriguing transfer sagas.
Manchester United will evidently be on the lookout for attacking reinforcements this winter, with the wide areas likely to be subject to an overhaul due to the infuriatingly inconsistent form displayed by the likes of Ashley Young and Nani at Old Trafford.
Arsenal have an abundance of attacking talent in central areas but could be looking to strengthen their threat from wide areas with Theo Walcott and Lukas Podolski having missed large spells of the 2013/14 campaign through injury, while North London rivals Tottenham could be set to invest yet more huge sums after enduring a toothless and ineffective start to the season.
Liverpool have been in formidable form in the last third of late, but summer arrivals Victor Moses and Iago Aspas have struggled to impose themselves at Anfield.
Chelsea are another team who appear to be particular blessed with a unique array of attacking midfield talent, but rumours continue to circulate concerning the futures of both Juan Mata and Belgian starlet Kevin de Bruyne.
Konoplyanka, known for his versatility and trickery and reportedly valued by his club at around the £15 million mark, would appear to possess the attributes required to become a huge asset to any of those aforementioned clubs.
