Forward: Olivier Giroud - Chelsea

The former Arsenal striker is out of contract in 8 months and can be a good signing for any club looking for a striker with proven abilities without burning a hole in their pocket.
Olivier Giroud signed up with Chelsea this January on an 18-month contract. His spell at the Stamford Bridge has been decent one, where he has scored quite a few crucial goals coming in as a late substitute.
He is yet to score in the league this season, but that doesn't seem to bother Turkish giants Besiktas who are actively monitoring his contract situation, according to reports from Turkey.
Forward: Anthony Martial - Manchester United

The 22-year-old attacker claims the final spot in this starting XI, to make it an all out French attack alongside his compatriot Giroud.
Anthony Martial has only made 3 starts this season in the league so far and with his contract expiring next summer clouds of uncertainty surround his future.
With his playing time limited under Jose Mourinho, it seems unlikely that the Frenchman is going to pen down a new deal at Old Trafford.
The prospect of Martial being one of the biggest free agents available next summer doesn't seem too far-fetched, given his current contract situation.
