Cristhian Mosquera has become Arsenal’s fifth signing of the off season after completing a move from Valencia.

The Gunners struck a initial fee of around £13million (€15million) with the La Liga side, as Mosquera signs a five-year deal in north London, with an option to extend by a further 12 months. The 21-year-old centre-back arrives with an excellent pedigree, and is recognised as one of the best young defenders in the Spanish top flight.
