I got Brother to play midfielder for me, Tidus and Wakka on the right and left strikers and Jumal at keeper. I want better defenders though, ones that can regularly steal the ball and launch it to my strikers. Any tips on where I could find some FA defenders worth signing?

Wedge can steal like no tomorrow, if you level him properly.

Where would I find him? :)

In Luca. At the stairs leading to the stadium. He's on the right, iirc. Biggs is opposite him, whichever side he's on. Wedge was my greatest player until Tidus far surpassed him. I stuck Tidus and Wakka outfront and had Wedge and Shuu in the back, and Wedge still stole the ball in like every encounter.

Then where can I find Shuu? I really want to get this team better, I'm sick of being outclassed a lot. I have found my new goalie is like impossible to score on. She's allowed 1 goal in like 30 attempts. <3 Super goalie.

Jumal is the second best goalie, stats-wise. Nimrook is the best, but I like Jumal so much and put so much time into him that I just benched Nimrook. He can't stop goals when he's sitting on my bench :p

Shuu is in the cafe at Luca. I forgot to pick her up when I started and she kept re-signing FOREVER. Longer than even Nimrook. But, that turned out to be a good thing, as she came to me with a FULL ability list :D I was so happy about that.

The only other members I haven't mentioned are Rin (he was in Shuu's place until she came around) and Zev Ronso. Zev's on the docks of Luca and when I was starting out he would steal and score like crazy. He isn't so great now that everyone else is so good, but he's never failed me as a center.

Jumal is the goalie I have now, it's not even funny how much better than Keepa he is. Super goalie is now my second favourite technique behind Sphere Shot. :)

Keepa's stats jump like mad at 99, but who's going to level that long?

I have to admit, I have Wedge and that Ronso now, neither one of them is really impressive. :(

Are there any better strikers than Wakka and Tidus that I can get? They're nice but not a guarantee. I have to get a lot closer with Wakka than I do with Tidus though. Sometimes I can score with Tidus from midfield. :O

For defense, I use Ropp (in Mi'hen Travel Agency) and Kiyuri (on the SS Winno), since they both have really great defensive stats. Ropp is arguably the best defender there is.

Anakin1980, I use Shaami (a Luca receptionist) as my other shooter; she has better stats than Tidus. But if you just want all around good players, any of the Kilika Beasts should suffice. They're all really good at their positions.

Sounds good to me, will have to hunt them down after I finish getting the Magus sisters.

My current lineup -
Left Fielder: Tidus
Right Fielder: Wakka
Midfielder: Naida
Left Defender: Ropp
Right Defender: Botta
Goalkeeper: Jumal
