#4 Olivier Giroud

Olivier Giroud is a 32-year-old centre-forward who plays for Chelsea in the Premier League. He has also played for France's national team 89 times since his debut in November 2011 and scored 35 goals.
Whilst Chelsea have the option to trigger a one-year extension on Giroud's contract, things aren't looking good for the Frenchman who has openly said that he would love to stay at Stamford Bridge for a lot longer.
Giroud has featured in 23 matches for Chelsea this season but has only scored twice and assisted four. For a centre-forward at a club the size of Chelsea, two goals in 23 games is simply unacceptable and is likely the main reason behind why they haven't engaged in contract talks with him yet.
Paris Saint-Germain are one of several high-profile clubs in Europe who are looking at signing Giroud this summer. A chance to get him on a free transfer is a great opportunity and also means that the club can put more into the player's wages to entice him.
