If you can't trust Walter Mazzarri with young talent, who can you trust? Oh wait. That's right. You can't trust him at all.
Inter Milan confirmed on their official site the capture of the 19-year-old right-back on loan from Chelsea. Wallace's agent, Frederico Moraes, said to Tuttomercatoweb.com, via Goal, "Wallace is truly very happy that things all went for the best and now he just wants to wear the Inter jersey as soon as possible."
There are a couple of issues about this deal if you're a Chelsea supporter.
The first is Mazzarri's track record playing younger players. He didn't really have much of one because when push came to shove, he picked the much older player to the inexperienced youngster who was arguably the better option.
You have to look at the objectives of a club before unleashing youngsters in Serie A. If you’re asking me to survive then all of the younger players can be used. However, if you want to finish in the top three then it becomes a lot more difficult.
If the 51-year-old Italian starts to run into trouble at the San Siro, he's going to do whatever it takes to win in the present. Inter President Massimo Moratti has a quick hook for his managers, so he's not going to waste any time sacking Mazzarri, like he did with Claudio Ranieri, Gian Piero Gasperini and Andrea Stramaccioni.
The injury to Javier Zanetti should mean more playing time for Wallace, but don't be surprised if Mazzarri relies on somebody like Yuto Nagatomo or even Jonathan when things start getting tight and his job is on the line.
Even more important, Mazzarri's style is only going to accentuate the attacking aspects of Wallace's game. The Brazilian will operate as a wing-back in Inter's 3-5-2 or 3-4-3 style. Mazzarri almost uses his wing-backs as wingers first and defenders second.
It shouldn't be an issue for the player tactically. On the other hand, that's not what you want from a Chelsea perspective.
The problem is that playing in that system doesn't force Wallace to go outside of his comfort zone too much. Ideally, you'd send him to a club that operates with a more common four-man defence. That would mean the player is being used as a full-back and having to stay back and defend more.
Instead, he's going to have even more licence to get forward and ignore tracking back.
Is a loan to Inter a good move for Wallace?
Young full-backs all have problems balancing the defensive duties with their desire to get forward and pump crosses into the box. It's only with experience they learn how to perfect that balance.
At Inter, Wallace is not going to get that kind of experience. He won't be the next incarnation of Dani Alves by any means; however, he is unlikely to make the proper all-round tactical improvement he should be at this stage in his career.
By the time he returns to Chelsea, he'll likely still run into the problems of getting too far up the pitch and leaving the back exposed down the right.
The goal of any loan move is to put your player in a position where he's playing every week and growing as much as a possible as a footballer. It's hard to say Chelsea have done either of those by sending Wallace to Inter.
