Arsenal have accidentally confirmed the signing of Cristhian Mosquera during the announcement of Noni Madueke's arrival.
The Gunners on Friday unveiled Madueke as their fourth summer signing, joining from Chelsea in a deal worth up to £52million. The winger follows Kepa Arrizabalaga, Martin Zubimendi and Christian Norgaard through the door as Mikel Arteta's summer spending soars past £200million.
