The Reds could be set for a busy end to the transfer window, which could also be the case for Liverpool's Premier League rivals. And we have rounded up the latest rumours relating to the rest of the 'big six, below. Nicolas Pepe's Arsenal career could be coming to an end as Besiktas edge closer to a deal for the Ivorian. Arriving at the Emirates during the summer of 2019 for a then club-record fee of £72m, Pepe has failed to live up to expectations and has fallen so far down the pecking order he spent the entirety of last season at Nice. has suggested Besiktas have made "great progress" over a deal for the 28-year-old, who has one year remaining on his contract. As a result, this is the Gunners' final chance to cash in before he becomes a free agent at the end of the campaign. Staying on the topic of Arsenal, Chelsea are said to be keen on recruiting Folarin Balogun from the Gunners. Balogun enjoyed a hugely successful loan spell in Ligue 1 with Reims last term, scoring 21 goals in 37 appearances, resulting in a number of clubs registering their interest in the 22-year-old. Chelsea are understood to be one of the sides eyeing a move, according to , and have held "tentative talks" with the player's advisers. Monaco are also understood to be in talks with Balogun, who is valued at £50m by Arsenal. Barcelona reportedly have an agreement in principle to sign Manchester City full-back Joao Cancelo. The Portuguese star fell out of favour midway through City's treble-winning season and subsequently spent the second half of 2022/23 at Bayern Munich. He is now set for another loan, this time at Barcelona, which will include a purchase option of €30m (£25m). Spanish outlet SPORT have stated Cancelo's switch will be finalised at the beginning of next week "at the latest." Manchester United boss Erik ten Hag has made clear Brandon Williams and Donny Van de Beek will not be considered for selection due to the possibility both players could leave the club before the September 1 transfer deadline. The pair were absent from the Red Devils' matchday squad for the second week in succession and this is likely to remain the case as United seek a solution over their futures. "Yesterday, the final training, 'H' (Harry Maguire) fell out with a small issue and after September 1 everything can change, but we need players who are totally with their heads in our team. And, I wouldn't say the players you just mentioned, they are not, but it's also obvious in this moment they are looking for something else," after United's 2-0 defeat at Tottenham Hotspur. "But when they are here, they always do their best and they do every training, Brandon, Donny, I am pleased with their performance and also pleased with their performance in pre-season, Brandon, Donny, and some more did a very good pre-season." Tottenham are believed to have held exploratory talks with Chelsea over a potential move for Romelu Lukaku. On the lookout for Harry Kane's long-term successor, have suggested Spurs have turned their attention to the Belgian forward. Despite contact being exchanged between the clubs, the above report adds this has not yet led to "anything concrete." It is added Chelsea are seeking €45m (£38m) for the former Everton and Manchester United marksman.
