Let's start from the end: Inter's activeties in the transfer market can get no more than four out of ten. Why? The youngster Juan is the only permanent acquisition; Thiago Motta and Viviano the only two players sold for good. The rest are just loanees coming and going: Palombo and Guarin came on loan, Jonathan was sent to Parma on loan, just like Coutinho to Espanol and Muntari to AC Milan. Too many loans mean two things: lack of funds and no plans for the future.
Palombo is a holding midfielder with a good shot who can combine well with a playmaker in a 4-4-2 formation. He can also play in the diamond's sides.
Fredy Guarin is a modern and versatile midfielder. He gets 10 in nothing but we can say he's between 7 and 8 in everything: he has stamina, good vision, nice touch, and makes always very clever runs and passes. He'd be perfect in a 4-3-3 formation but has quality to settle easily in any other scheme, unless you asked him to play in the Cambiasso or in the Sneijder positions, where he'd be less effective.
Juan. Inter bought this 21-year defender from Internacional Porto Alegre "Because he is one of the most promising youngster in Brazil". With him and Ranocchia Inter has a pair of centre-backs who can lead the defence for a decade. More likely - if Ranieri will stay in charge - to see both leaving in the summer.
Thiago Motta. Inter's squad had only two playmakers capable to play in front of the back four: Motta and Poli. Different players but the only two who could play there. Ranieri never tried in that role the 22-year Poli (another loanee), he trusted only the 30-year Motta. The Brazilian was one of the key-factor in the recent seven wins streak: sold. And no playmaker arrived to replace him. It looks like a [more modest] sequel of Samuel Eto'o's selling strategy.
Coutinho & Jonathan. None of the two was given a fair chance by Ranieri. Juan is tipped to be the next casualty.
Muntari. AC Milan are offering Sulley the (temporary) chance to resurrect his career after being marginalised at Inter in the last two seasons and failing to impress during the six month spell at Sunderland in 2011.
Viviano. Forced to let go to Palermo to avoid any pressure on Julio Cesar and Castellazzi. The former Bologna goalkeeper had the potential to become Inter's new number one for the next ten years. If Roberto Mancini with Francesco Toldo would have adopted Ranieri's way, Julio Cesar would be still at Chievo today.
PS Maybe 4/10 is too generous.
