We are a long way from reaching top 5 in Europe, I'm still thinking of top 4 in Premiership. I really think we need more drive in Midfield this season. As Ole says we need a "Bryan Robson" in there.Depends what you mean by 'problems' Will it close the gap enough taht we challenge for the title? Probably not. Will it give us enough of a boost to look at a 3rd/4th place finish? Probably yes.
We aren't going to address everything we need to be a top 5 in Europe type of power in one window so it really does depend on what you class as our problems and what you want to address by fixing them. Our current problem, in my mind, is getting back to a top 3/4 team and giving ourselves a platform to build on next summer and push on to a top 2 challenge.
I really think that our aim should be to reach 84/85 points in Premiership this season.
