Unsure: Allegri is under pressure again and doesn't seem to know his best team
Since defeating Celtic 2-0 in September, Massimiliano Allegri hasn't started the same team twice.
He's tinkered with formations, positions and attacking combinations—and still his team can't find their feet domestically.
Granted some of his selections—like the Celtic game—were influenced by a growing injury list and suspensions, but the only mainstay in the team since the first tie has been centre-back Cristian Zapata.
What is most worrying, however, is Allegri's indecision over who to start in the attacking positions.
Alessandro Matri, Mario Balotelli and Kaka have started the last two matches together, while before that it was Kaka and Robinho, and before that Kaka, Balotelli and Valter Birsa.
You get the idea—when Kaka is fit, he starts.
Who to start alongside the Brazilian, and in what system, is Allegri's main problem—mightn't it be better to leave him out altogether?
Well, their two wins since the Celtic game have both come when Kaka didn't start but, in general, he's looked better every passing game lately.
When Kaka wasn't starting the attacking permutations have been Balotelli—Robinho—Birsa, Matri—Robinho—Birsa, Matri—Robinho, Balotelli—Robinho and Matri—Balotelli—Birsa.
That said, the Rossoneri scored 11 goals in the seven games he didn't start, compared to only four in the six games he's started since returning to the line-up against Barcelona.
Indecisiveness permeates Allegri's team selection every other week; Celtic must hope that, if the 46-year-old is once again destined to turn around Milan's season, he doesn't begin on Tuesday.
