How could Arsenal line up against Southampton with new signings Shkodran Mustafi and Lucas Perez?

Arsenal endured, perhaps, their most-maligned transfer window in recent history this summer, which culminated in manager Arsene Wenger breaking out the club's chequebook to sign defender Shkodran Mustafi and striker Lucas Perez. The duo joined for a combined fee of more than £50m ($66.5m) and have linked up with fellow new boys Granit Xhaka, Takuma Asano and Rob Holding at the Emirates Stadium.

So, now Arsenal have their new recruits with them, how will the Gunners line up against Southampton at the Emirates? Here, IBTimes UK look ahead to Wenger's possible team selection for the match on Saturday (10 September).

After months of dithering, Wenger decided to splash the cash in the last few days of the transfer window, bringing in Mustafi and Perez. The German centre-back arrived at the club from Valencia and his class should go a long way towards shoring up the Gunners' fragile-looking back-line.

Young centre-back Rob Holding has earned plenty of plaudits in the opening weeks of the season but after spending around £35m ($46.6m) on Mustafi, its seems inevitable he will replace the 20-year-old Englishman. Mustafi cut his teeth in English football at Everton as a teenager and should, therefore, have few problems adjusting to the pace of the Premier League.

Meanwhile, the 27-year-old Spaniard, who enjoyed a stellar campaign at Deportivo de La Coruna last season, ought to provide a more mobile alternative to Oliver Giroud up front. The Frenchman has come in for some severe criticism in recent months and Perez's arrival may see him lose his status as Wenger's go-to centre-forward.

Whether Perez is the long-term answer to Arsenal's striker troubles, though, remains to be seen. He has enjoyed a nomadic career to date and has only really come to the fore over the last 12 months, suggesting he has a great deal still to prove at the Emirates.
