Arshavin and Dzagoev were more central and certainly deeper for me. Countless times Kerzhakov and after him Kokorin recieved the ball on the right and wasted time and chances cutting in on to their left.
Kokorin only came on late for Dzagoev though. The sub looked left footed and he replaced a right footer on the right. For all Dzagoev was technically on the right side for his footedness, he didn't half slice right footed shots wide from good right sided positions.
There were a maybe three of them, each time he needed to shoot across goal but went for the near post and missed the goal totally.
Arshavin floated more between left and central which made sense, he was the left sided attacker though with Kerzakhov the main central player.
It was an interesting example of going against the accepted tactical norm though by playing wide players on the side of their footedness. You saw both the advantages and disadvantages though. The advantage is the true width you get which can stretch a team and the pace you can break at. You are sprinting in straighter lines on your favoured foot, none of this checking to come inside and losing momentum which can allow a defender to recover the lost yards on you.
So that was a success, especially as the Czechs are not quick at the back and were not quick at reacting to losing possession. The Russians were streaking away in space an awful lot for a game at this level.
But you saw the downside too. When a wide player does play on his wrong foot and he comes inside, he has a decent amount of the goal to shoot at. Dzagoev for example was running a wide channel and the closer he was getting to goal, the narrower his angles were getting. It needs more composed finishing in that situation and of course the Russians didn't really do this.
The other downside comes with the width. It gives you attacking scope but opens you up defensively when you lose the ball and you take longer to narrow the play. Now I think Russia looked pretty tight tonight apart from going to sleep and allowing the pass for the Czech goal, however I will be interested to see if they play reverse wingers for pragmatic purposes when they play a decent team in the knock-out stages.
