My two unknown and go to guys as subs of my 1st team strikers are Burak and Pukki. The first one is a vice-Cavani for me, cheap as hell, decent speed, but strong as an ox despite a "mediocre" stability stat (app 80+) compared to 1st class defenders. Decent finishing and heading too.
Pukki is a small, techinical player, whom for peanuts will bang you a dozen of goals.
As LB-RB, Inoha... Just humor me on this one... And my all time favorite... SIGEDIZ, shit player, but high defense, and very high speed, just use him to break up attacks.
Thanks Burak looks good. If you want another like him, check out Umut Bulut, as I mentioned above. They seem very similar.
Pukki looks decent too, but I use AMFs and he doesn't play that position so he wouldn't be much use to me.
Also, by the way, one of my favourites mentioned above, Ludovic, is suddenly no longer in the game. Not sure why, but he disappeared.
A couple others to add as well:
Nivaldo - CB - 79 overall. For some reason his price dropped drastically in the market and I bought him for approx half price. Not sure why this happens, but just saying that if you want an amazing deal on a player look at the graphs (painstakingly) for these massive price drops. Price was around 4 million and suddenly dropped to 1.7 million. Or am I missing something...? Maybe his stats were reduced, but either way for the price he was a great bargain.
Vellar - My other CB. One of the cheapest players you can get who has the "lunging tackle" special card. Good all around CB.
Sogrocan - GK - 91 mentality means that unlike a lot of other GKs he doesn't suffer from fatigue late in matches. Stamina is only 55, but mentality determines how a player responds to fatigue. High mentality means even when he is tired he plays relatively well.
Gedo - AMF but played as a CF has some very good skills for the price. Ignore his over all stat and look at what skills he has that are important, including adv stiker and super sub. He may be only 67 overall as a CF, but look at these stats:
responsiveness 86 (very important for a striker)
shot accuracy 85
jump 75
header 74 (not terrible in other words)
all his other stats are mediocre, but my point is that all around he doesn't have a huge weakness and is cheap like dirt. Decent attack, dribble, speed, technique, teamwork, passing. Not a starter necessarily, but very effective as a super sub or for games against weaker opponents when you want to start less expensive players.
Similarily, Salpingidis is cheap and all around a good player with super sub and adv striker to boot. Slightly better balance and heading acc than Gedo, but 7 form and also 86 for responsiveness (this really helps for strikers IMO).
I've often won or drawn games by bringing on this inexpensive duo of super subs late in the match.
