Mikel Arteta often stresses his desire for Arsenal to be “unpredictable” in how they set up - and the signings of Noni Madueke and Viktor Gyokeres will certainly help that. Gyokeres, who scored a remarkable 54 goals in 52 games for Sporting last season, offers an alternative option up front to Gabriel Jesus and Kai Havertz.

Arsenal will sign their second player from London rivals Chelsea this summer when Noni Madueke’s transfer is finalised.

Twomey: The success of Chelsea’s recruitment model depends just as much on their ability to sell profitably as it does on buying intelligently. Every player who is not absolutely integral to the team Maresca is building has a price, and Madueke has never managed to make himself indispensable at Stamford Bridge.
