Alex Iwobi trains with the first-team ahead of Southampton clash

Arsenal have been handed a major boost ahead of their game against Southampton on Saturday (10 September) with Alex Iwobi returning to training after missing the last two games with a thigh injury. The Nigerian striker picked up the knock during the Gunners' season opener against Liverpool, and consequently missed the games against Leicester City and Watford.

Arsene Wenger will have another forward option at his disposal as the north London club seek their second win of the season. They have already fallen behind their rivals Manchester United, Chelsea and Manchester City, who have won all three of their games thus far leaving Arsenal five points adrift.

Olivier Giroud lacked match fitness for the first three games of the Premier League season, which saw Alexis Sanchez deployed as the central striker. Theo Walcott and Alex Oxlade-Chamberlain were used in the wide areas, but the Frenchman played for France during the international break and is likely to return to the starting lineup for the game against the Saints on Saturday.

Apart from Iwobi, late summer arrivals Shkodran Mustafi and Lucas Perez were also pictured training with the rest of the first-team squad on Wednesday and are likely to play a part in the game against Southampton. The German defender shared a picture with his compatriot Mesut Ozil after his first week of training with the club began at Arsenal's London Colney facility.

"My first training week with Arsenal... Some familiar faces on the pitch," Mustafi wrote on his official Twitter account alongside a picture with Ozil.

Rob Holding is likely to make way to accommodate the Germany international, despite being impressive in all the games. He has started all three games thus far this season and received special praise from the manager following his performances against Leicester and Watford alongside Laurent Koscielny.
