Didn't Pompey always play decent football when they could though? I'm not saying they religiously stuck to it like Swansea, but I never had them down as Bolton esque cloggers. They simply struck me as doing what they needed to do at times, and always had some flair in the side that was given license to express itself.
Same with Harry's West Ham, they always expressed themselves and they had flair in the team, so I wasn't surprised that we play good football under him. And I don't think it's a good example to use for Moyes. He is defensive by nature. He is reactive. He often tries to shut up shop rather than maintain possession. He is cautious. I highly doubt that he would change if he came here.
On the one hand, his Everton team can score some nice goals. Just off the top of my head, Pienaar's 4th at Old Trafford was a nice goal. If we scored that we'd all be very impressed. So I'm sure our players could too. But it's his personality, it's his nature to be reactive and cautious, and that's what worries me. Harry wasn't a cautious guy in terms of his footballing philosophy.
I asked this on here when Moyes' name sprung up before but I don't think I ever got a response. Has there ever been a manager known for being defensive that's ever gone to a club where good football is expected, and actually delivered it with success? I genuinely can't think of one.
