Chelsea have joined the race to sign Brighton and Hove Albion midfielder Yasin Ayari, while Barcelona and Real Madrid are monitoring Aston Villa’s Johan Manzambi as European clubs begin assessing their transfer options ahead of the January window.

Ayari, 23, has attracted interest from Chelsea and Turkish giants Galatasaray, with uncertainty surrounding his contract situation at Brighton potentially opening the door to a move.

The Sweden international has emerged as a player of interest for Chelsea as they consider strengthening their midfield options. However, competition from Galatasaray could complicate their pursuit of the former AIK midfielder.

Meanwhile, Liverpool are not planning to rush into contract negotiations with Alexis Mac Allister despite the Argentine midfielder’s improved performances this season.

The 27-year-old has regained form at Anfield, but the Premier League champions are reportedly in no hurry to begin discussions over a new deal.

Manchester United are also among several European clubs monitoring FC Twente defender Ruud Nijstad.

The 18-year-old Dutch centre-back is regarded as a promising defensive prospect, with his performances attracting interest from clubs looking to invest in young talent.

At Aston Villa, Manzambi has reportedly caught the attention of Spanish giants Barcelona and Real Madrid following an impressive start to his career at the Premier League club.

The 21-year-old Switzerland international’s progress has placed him on the radar of two of Europe’s biggest clubs, although no completed deal has been indicated.

Sunderland, meanwhile, are preparing to renew their pursuit of Sporting CP winger Geny Catamo when the transfer window opens in January.

The 25-year-old Mozambique international has previously attracted interest from the English club, who are considering another bid to strengthen their attacking options. Competition from other clubs could influence Sunderland’s chances of securing his signature.

Everton are also assessing potential additions to their forward line, with Dinamo Zagreb striker Dion Beljo among the players under consideration.

The 24-year-old Croatia international is one of several attacking options being monitored by the Merseyside club ahead of the January window.

Liverpool are also among the clubs interested in Mexican teenager Gilberto Mora, who plays for Tijuana.

The 18-year-old midfielder has attracted attention from several leading European sides, with his age and potential making him an attractive prospect for clubs looking to strengthen their squads for the future.

Gyokeres faces Arsenal exit

At Arsenal, questions have emerged over the future of striker Viktor Gyokeres, with the club reportedly willing to consider his departure if they can recover the £55 million they paid to sign him.

The 28-year-old Sweden international could leave the Emirates Stadium at the end of the season rather than during the January window, as Arsenal assess their options and potential interest from other clubs.

Arsenal are also leading the race among Premier League sides to sign Turkey international Can Uzun from Eintracht Frankfurt.

The 20-year-old attacking midfielder has emerged as a transfer target for the Gunners as they look to add creativity and attacking quality to their squad.

Elsewhere, Brazil forward Vinicius Junior has reportedly changed his outlook on a potential move to England.

The 26-year-old Real Madrid star was strongly tempted by the prospect of joining Arsenal during the summer transfer window but now hopes to remain at the Spanish club for the rest of his career.

His reported desire to continue at the Santiago Bernabeu would make any potential move to the Premier League difficult, despite Arsenal’s previous interest.

With the January transfer window approaching, clubs across Europe are continuing to monitor emerging talents, assess contract situations and identify possible reinforcements, although the reported interest in these players has yet to translate into confirmed transfers.
