Could be, depends upon what you class as phases of play, whether he got back on side and if the part of the body which could score the ball was offside or not...
...got to love the offside rule eh, simple in it's aim, complicated by FIFA.
Hard to tell, from the close up angles we don't see anything of serious note. However there where some wider angles (mainly the one from the touchline) which showed the Portugal player make a run from behind and as he went by the 11 of Spain raise his elbow as if to block the Spanish player and it seemed as if he did catch him with the elbow.
Now under the laws of the game, if a player strikes his opponent (i.e. punch, slap...even tickle) deliberately above the chest then it is a straight red card. The ref obviously felt it was a deliberate motion towards the Spanish no.11, connecting above the chest and had no other choice but to show the red, regardless of how little contact was made. The problem is that TV pictures aren't conclusive enough for us to make a solid call, the close up missed the point of impact while the zoomed out picture's make it hard to see how strong a hit was made (if any)
Yes the no.11 made a meal of it (not going to deny that), but no more than the other 99.9999% of the players at the world cup would have done. I'm now past the stage of moaning about it. I'm happy enough to cheer a penalty County may have won because our player took a dive, to complain about it when the boot is on the other foot seems rather hypocritical to me.
I think the dutch have been cruising too, Brazil isn't that good to be honest the chile game was the only one so far that lived up to Brazils expectations.
Our midfield will be broken, it seems. Elano still seems to be injured and his substitute, Ramires, will miss because of a second yellow. Word is Felipe Melo won't recover (yes!!) from Pepe's foul as well.
So it might be Daniel Alves and Josué in the middle, which is not exactly a strong midfield.
I think both teams are even. None had a real challenge yet, none played all they know yet. Friday would be a good opportunity to see what they can do.
