yeah this was very apparent - parker went into panic mode and headed straight for the goal mouth to join the 4-5 others already there. he had cleverly in his sights but he made the wrong decision to defend so deep. being a shorty himself he would be more useful waiting for the "second ball" outside the box.
Agreed... In fact I think a lot of players were all over the place for this goal.
It starts with Bale closing down their CB and so leaving Rafael free, which leads Dembele to get dragged over to the left touchline and Parker to get dragged over too, leaving a gigantic gap in the middle of the park for Carrick to receive the ball in. Parker seems totally unaware of Carrick and follows the ball instead, then casually jogs back as the ball gets spread out to United's left wing... Dawson gets sucked out to the unmarked Carrick, thus leaving RVP free, but not sure that was a mistake - he was just outnumbered... Naughton does the right thing in my view by springting back to cover RVP and Kagawa in the middle, as they'd both got goalside of Dawson and Caulker respectively (who looked rather nonchalant in letting Kagawa run by him)... but this leaves Cleverley free, and I have no idea what Parker is doing in a) jogging casually back when he's supposed to be our DM, and b) eventually running towards Kagawa when there's already two players on him but no-one on Cleverley, and c) Not closing down Cleverley quickly once he receives the ball.
So overall I think Parker was the biggest culprit, though Dawson and Walker were both at fault IMO for not getting close enough to RVP and / or Welbeck once Cleverley received the ball in space.
I do think Parker had a good game defensively in terms of pressing and tackling, but was this goal indicative of his weakness in comparison to Sandro? I think Sandro's a bit more controlled in his positioning, in comparison to Parker who tends to run around a bit more maniacally (e.g. when following the ball to Kagawa rather than recognising that Caulker and Naughton were already near him and Carrick was in acres of space).
I actually think Parker and Carrick would compliment each other fantastically well; it's a shame they've never had a run together for England.
