Arsenal are really looking to stamp their authority on this summer’s transfer window as Mikel Arteta prepares for another Premier League title challenge. The Gunners could be set to land three of their top targets by the end of this week, with Viktor Gyokeres, their No1 priority, nearing a move to north London. Talks with Sporting seemed to have hit a snag over “financial discrepancies”, but now, those fears seem to have been allayed, and the deal could go through by the end of this week. Elsewhere, Noni Madueke’s £52million from Chelsea is almost a formality, while Cristhian Mosquera has undergone a medical ahead of his switch from Valencia.
