I think it's because there's often no pattern to the game. Pardew has it scribbled on a post it somewhere "Score 3 goals without reply in the first phase. Bring on Shola after 60 minutes (second phase). Win game. If phase one hasn't happened, go to second phase anyway. Win game."
People read way too much into what's said in the press. If there was one thing I'd wish our fans would wise up about, its the press and what's said in it. All managers make throw away comments and contradict themself. They use the press as they see fit and don't really care if they do contradict themself. They probably expect a bit of common sense from fans in what they read into it or have more important things to think about. Pardew will know Shola is getting pelters again, but he'll also know Mike may not back him in the summer again and he may be left with Shola as his 2nd choice striker. He isn't going to hang the lad out to dry.
Don't get me wrong if he continues to have Ameobi as his back up striker when we have other options then we have a major problem. Its a case of picking and choosing comments though. Pardew also said the other day we need 2 strikers in the summer. So that's two new strikers, plus Cisse, he likes Campbell. Shola errr...............So what he actually wants and what he will say pubically about his players are two very different things.
SAF said recently that Rooney was happy at the club and was going no where. A few weeks later he admits he's been to see him on a few occasions, he isn't happy about being subbed, a top form Rooney wouldn't get subbed and he wants to leave. They do as they please, its nothing to get excited about!
