Gyan Asamoah and Drogba. Can be obtained quite easily & are both frighteningly good (obvs.), complement each other too. Drogba's stats are still as good as they were on PES like 4 years ago, as long as you play him enough they won't drop. Also Maxi Rodriguez can be obtained quite easily.
F. Fernandez from Napoli developing into a strong defender. Also check out LMF Konoplyanka, looks like he will develop into a terrific winger, rated overall 79 at age 23, very quick and possesses almost every single flair special ability you can have. I also picked up LMF/LB Shea who is very tall and strong, looks like a good player to have for those matches when you need some extra height/strength covering your defense, and hopefully will also be good going forward, still 22 so plenty of time to develop.
I picked up CB Baloy who has overall rating of 85 (defence only 77 but high jump stats, body balance, good height, response etc). Aged 31 but good to have on bench and play when on form.
