Javi would settle fast, if you watch Bilbao, he has no problems being combative, or playing at a quick tempo; In fact he is actually too combative, good luck to whichever oppo player tries to bully him with a hard tackle if he was to come to the Prem, he'd get smashed back twice as hard.
Modric at 40m is a no brainer. Find me another playmaker of his class for less than 30 and they become alternative. But the truth it, players of his calibre are few and far between. So if there is a chance of getting him, it should be taken.
Martinez isn't a playmaker either. More a mix of Carrick and Roy Keane.
