Arsenal are expected to seal four transfer deals in the final 24 hours of the window, Football Insider sources understand.

The north Londoners are on the brink of completing the signings of Nigerian teenage duo Kelechi Nwakali and Samuel Chukwueze.

They posed with Arsenal manager Arsene Wenger, chief executive Ivan Gazidis and former Gunners striker Nwankwo Kanu at the club’s London Colney headquarters on Friday as they finalised the paperwork on a double deal that could cost £4million.

The double arrival at Emirates Stadium is set to be followed by a double departure.

Mathieu Debuchy and Serge Gnabry are both expected to leave Arsenal by the 11pm transfer deadline on Monday night.

Debuchy is close to joining Aston Villa on loan, but he was in limbo earlier on Sunday as he waited for terms to be finalised. Sunderland and Bayer Leverkusen are waiting in the wings in case the deal falls through.

Serge Gnabry is set to head out on loan again following the end of his spell at West Brom

Red alert: Gnabry is set to clinch a loan move in the final hours of the window

Wenger admitted in the wake of the Gunners’ 2-1 FA Cup fourth-round win over Burnley that Gnabry is set to head out on loan in the final hours of the window.

The manager is keen for the young winger to get some first-experience after Arsenal recalled him from his disastrous loan spell at West Brom earlier this month.

Gnabry is likely to move to a Championship club, with Brighton, Fulham and Charlton among those interesting in taking him for the rest of the season.
