To beat bus parkers, you need quality up front, which is expensive. Or you need bodies in the box, which requires some kind of insurance in case the ball breaks loose, either with a quick defence, a quick midfield, or both. Not some magical ingredient which is called creativity (Lucas used to be abused for lacking all sorts of qualities, which were defined by virtue of Lucas not having them). I think Spearing passes the ball marginally quicker than Mascherano (I think I was the first to point this out), which can make more sense in a team geared for that. But it doesn't mean Lucas/Spearing was a better midfield than Lucas/Mascherano. They make different kinds of sense.
I am going by the results of the partnerships. The theory behind a partnership is for before the game begins. Some can make sense in theory and fail miserablely when impemented in practice. Masch/Lucas seemed to affect the whole balance of the team and as a result, we were very poor as a team. Some of that can be attributed to Masch and Lucas not working well enough as I explained in my previous posts.
On the other hand, when Spearing an Lucas played, the whole team had the right balance. No one complained about Spearing and everyone began raving about ucas and the whole team played great.
In the last 3 years, this is the only period where we have remotely looked like a great team for a sustained period of time. The fact that this was achievable with an average jack of all trades like Spearing shows that it's all about the team and all about the balance.
Spearing/Lucas were our best partnership in the last 3 years on results. That shows that Spearing has a place in the squad and can slot into the team and be a valuable memeber of a team that looks like world beaters. Asking for him to be one of the main cogs of the team is a different story but you would expect that to be the role for someone else who isn't just a squad player.
