Isn't that the approach Rafa tried? We need to improve now so I would like to see more than one top signing. We have plenty of decent youngsters already.
Lol
I must be writing like mud today:
I meant we have all the youngsters at the club already: just need phased into the 1st team over next two years(if they can cope)
We have a young spine, mixed with some quality old timers in the senior squad. Now we need only buy very high quality when we can get them.
Under Rafa (and I was happy enough with him without idolizing every move he made just like any manager) I believe we bought players for the sake of buying players sometimes: just adds to the wage bill without adding anything to the 1st team. I have not thought that of KD because it was his first year. I WILL think that if he runs out & buys 4 more players this summer who are no better than current in reaction to a few impatient & frustrated (understandably) fans.
Wether you are in the "this years crop will come good" or "this years buys were a dreadful mistake" camp; the answer isn't "let's go and take the same gamble this summer"
You'll end up with another disjointed team next year.
So I'm saying only buy a player if he is world class or through long term injury or catastrophic loss of form (from someone we've already got)we have no choice but to gamble (educated I would hope) in the absence of a world class alternative.
I truly believe the following:
This team is not bad.
This team with a few exceptions(team wise) has not performed badly.
It is ok to criticise an individuals form in the first year but not ok to write that player off.(next years fine

Any squad looks to improve: and improve to world class standard when the opportunity arises. Patience is needed.
Everyone seems to be able to rhyme off a list of 7 players "better than we have" that we shoulda, woulda, coulda got.
If it was truly that easy we wouldn't be two decades and 7 managers on from our last title.
