5. Radamel Falcao
Another striker in our countdown is Radamel Falcao. He was a sensation at Atletico Madrid and showed remarkable performance in the World Cup as well. AS Monaco came rushing to buy this world class striker, only to see that Falcao would become plagued with injuries, which is haunting him till date. He was loaned to Manchester United by Monaco in the hopes that United could bring him back to form, but that plan backfired since his form got even worse. He is now at loan in Chelsea, where he isn’t making significant progress honestly speaking!
