Arsenal accidentally leak new signing that nobody knew about after announcing Noni Madueke

Arsenal may have announced their fourth signing of the summer but the Gunners appear to have accidentally leaked another arrival.

The North London have been extremely busy in the transfer market, bringing in Martin Zubimendi, Christian Norgaard and Kepa Arrizabalaga - before snapping up Noni Madueke from Chelsea for a fee of £48 million and handing him a five-year deal.

Arsenal are still actively trying to do a deal for Sporting CP striker Viktor Gyokeres but are still at odds over the add-ons arrangement.

However, a fifth acquisition looks to have been confirmed after an error on social media.

On image site Getty, fans noticed that pictures of Spain and Valencia centre-back Cristhian Mosquera were uploaded alongside snaps of Madueke doing his mandatory interviews, before being taken down.

The 21-year-old was pictured smiling in Arsenal's training kit while speaking to a member of the club's media team.

Plenty of fans picked up on the mistake, which almost definitely indicates that an official announcement is on the way to confirm Mosquera's arrival.

Earlier this week, Fabrizio Romano revealed that a Wednesday medical was pencilled in for the Spain Under 21 international, who will join for a fee €15m plus add-ons as part of a long-term contract.

Madueke, meanwhile has expressed his delight over the transfer being completed, having grew up in North London and played in the youth ranks at Arsenal's rivals Spurs before signing for PSV.

"I'm somebody who goes with my gut feeling a lot of the time and I feel like it's steered me in the right direction so far," he told the club's official website.

"So, I don't think it's going to be any different here. I think it's going to be a great success and I'm really happy to be here.

“I’ve just been relaxed, waiting for the green light and when I came in today, it all felt real. I'm really happy and really proud, so it's a great moment for me. It's great to go back home, be with my mum, my dad. I know my mum misses me in the house!"
