“Arguably, they’re the best team in the league at the moment,” Sporting KC coach Peter Vermes said about Montreal Impact. Whereas there is an opportunity that Montreal will drop ten guys within 30 yards of their goal, such as Chicago Fire did, albeit midfielder Graham Zusi “don’t think it’s their style really to sit back,” the question is: can KC's defense control Marco Di Vaio? Sit down and play counterattack toward Di Vaio was a key of Montreal Impact 4-0-0 stretch. KC’s defense has back on track to become Sporting’s strength after a very slow start, shutting out both Chicago Fire and New England Revolution. Against Fire, KC did not allow a single shot on target for the seventh time in club history. That back four should see the come back of MLS 2012 Defender of the Year center back Matt Besler, that went from a big performance with USMNT. They are hoping right back Chance Myers too could return as well, after a leg injury, though newcomer Mechack Jerome played a solid game in place of Myers. On the other full-back spot is Seth Sinovic, a solid defender also good going forward. The Aurelien Collin-Matt Besler central duo is one of best central pairing on the whole MLS. How this bunch can contain Di Vaio? Impact No.1 threat plays around the offside line. He's been called for offside 16 times through the first four games of this season. So, specially if Pete Vermes’ thoughts will be to play an offensive oriented game, KC’s defensive line will have to pay attention playing high up, in the way to chase Di Vaio. Playing 2vs1 in the middle, Besler and Collin will have to cover Di Vaio in advance with one of them, preventing him from get balls, while the other center back will have to cover the deepth. When the ball will be lost in attack, if Sporting’s first line will be not able to gain back possession quickly, defensive line will have to read the situation and react immediately, collapsing back as soon as possible in the way to avoid long and dangerous balls on its back for Di Vaio.
