Royal Ginger This is exactly the problem with the seeming desperation to have Siggs back. Of course id love to see him in the hoops again, but we'd have to totally change the way we play to fit him in. It's going to mean playing 1 striker, favoring protecting the defense, and at the moment we don't really have anyone capable of playing lone striker. (Alf at a stretch). We'd need someone more like Long than Defoe.
I think this is a very blinkered way of looking at it. We played largely the same way when we had him, but with a slightly different formation. I see no reason we'd need to change a whole lot to fit him in. In fact I'd argue we NEED to change to the sort of style that he'd be a good fit in, to have much chance of survival. I'd say it's our current formation that would need more signings to make work than switching.
Currently, we'd be relying on Karacan to come back from injury better than ever. One of our biggest weaknesses over the last couple of years has been retention of possession. You can guarantee that'll be harder in the Prem. The less we have the ball, the less chance we have of scoring and the more chance we have of conceeding. And attackers are far better in the Prem.
I think we'd need to bolster our central midfield with a really quality player to keep with 4-4-2. Our wingers should do ok still, that's one of our positions of strength. But upfront, we look weak. Roberts came in and looked a cut above. But he is still 34. Can we rely on him being able to carry out attack all season? Doubtful. Hunt is a great squad player for the Prem, but he's not a starter. ALF isn't ready and Church simply isn't good enough. So we need at least one more striker, preferably two, to play 4-4-2. Then you look at our full backs and centrebacks. All performed really well last season, but it's a massive ask to expect all of them to step up. Ideally we need two new full backs and a new centreback, if not two. That's to cope with the extra pressure they're going to come under as we score less and conceed more possession.
Bring in Sig, and we only need the one striker, as Roberts, Hunt & ALF will be fine as back up and late game subs to go more attacking. Bring in Sig and we don't need a top quality midfielder, as Jem and Ledge should be good enough, to do the drity defensive work without worrying about pushing forward to help win games as much. Bring in Sig and our defence will be under less pressure for that reason and perhaps we can get away with fewer, or at least less expensive additions.
We can't afford to go into the Prem as a one trick pony totally dependent on getting the ball wide and hitting teams on the break. We need more threat through the middle and better ability to retain possession.
4-2-3-1 will protect us at the back and make it harder to beat us. Help us retain possession better. And also play into our strengths of hitting teams on the break hard from wide. And it also plays to our fitness, wearing down teams and allowing us to switch to 4-4-2 late on with ALF, or Hunt coming on to go out and open up for the win in the dying minutes.
That's just the way I see it though.
