Arsenal have received a massive boost as Laurent Koscielny, Mikel Arteta and David Ospina are expected to be available ahead of their crucial Premier League fixture against Tottenham Hotspur. This will give some much needed respite to the otherwise threadbare squad, who missed out on 10 players against Bayern Munich in the mid-week.

Koscielny has a hip problem, but should be available to start while Arteta has returned to full training and will need to work on his fitness to regain his position. According to The Telegraph, Koscielny could have played against Bayern as the injury was not too serious, but Arsene Wenger decided to rest him in Europe and play him in the domestic league.

Gabriel started in place of the Frenchman and was culpable for the first goal where he failed to play Robert Lewandowski offside, who had a clear shot on goal. Meanwhile, Ospina is also back in full training and is likely to feature on the Arsenal bench this weekend, replacing Matthew Macey.

Tomas Rosicky, who underwent a knee surgery this summer, has been cleared to start running and the Czech Republic international would be back in full training in due course of time. However, Jack Wilshere and Danny Welbeck will not be available until the new year, crunching the Gunners's options in the midfield and up front.

Arteta's arrival will also give them some depth in the midfield and allow Wenger to shift Santi Cazorla to the right if need be, given his lack of options in that position. Aaron Ramsey, Hector Bellerin and Alex Oxlade-Chamberlain are expected to be back after the international break, while Theo Walcott, who has a calf injury will be out for another month.

Olivier Giroud was taken off before the end of the game against Bayern, in a humiliating 5-1 loss for the English giants, with the Frenchman being their only fit centre-forward. The 29-year-old has taken his chances well, scoring in each of Arsenal's last two games against Swansea and in midweek and will need to play an important role should the Gunners have to get the better of Spurs.
