Marchisio, Momo and Melo are not all very similar defensive midfielders.
Momo, it is true, is not trustworthy passing the ball over distance, especially when under pressure to deliver a decent ball, with no easy options near him, only forwards to aim for. But he is a beast. A player who can singlehandedly prevent any opposition player passing him for an entire game. He also reads the play quickly and decisively, making important interceptions every time he plays. He has decent pace, zero regard for his personal well being and the spirit of a zulu cross viking.
Marchisio can defend with decent technique and moderate strength. He can also run with the ball, pass and shoot. He reminds me of how Tardelli turns out on Pro Evolution if you snap him up as a youngster and play him to death. Can't say that he is world class in one particular area, though he could become a world class all rounder. Able to defend and attack with potency. He is italian...which matters. Its wonderful to see Melo and Diego in the squad, and I am happy for them to be part of the team we are building, slowly but surely, and damn expensively, but...it is important for us to make use of our talented youngsters.
Melo is the most aggressive of the trio, cheekier, nastier, and physically robust enough to give most players a hard time if he is marking them. His passing seems high quality, and together with Chiellini and Momo, he creates a bulging muscle in front of our goal and towards the midfield. I know the least about him, in comparison to the other two. but at 21M he will be starting. And it cant be a bad thing to have a regular i the brazilian national team in our team.
If Diego wasn't so offensive and talented, and Melo and Marchisio couldnt pass and were Infantry like Momo, I would agree with some of the people who have posted in this thread, and say that more creativity is needed. Which would lead e to suggesting Tiago is given more of a chance, as he did a sterling job in a 3 man midfield at chelsea a few years back, and also Camo...but Camo's is not a central midfielder. He cannot defend, every tackle back is a foul, often petulant rather than mistimed. He can play only if we shift to a 4-2-3-1 formation...like this:>
Melo Momo
Camo Giovinco
Diego
Trez Amauri
that would be a wicked formation, but I prefer to play the 4-3-1-2 and include Marchiso...
Poulsen and Zanetti are our two defensive midfield backups, and as we play 3 defensive mids, we need at least those two...Almiron should be sold, or loaned. Tiago...i am unsure as to why he is staying. Same with Camo....neither look likely to stake a claim for a first team place.
