Carroll and Downing are the two signings that stick out like a sore thumb for Kenny. I still think Downing has been decent and can become a good player for us. Carroll on the other hand is much worse. Hefty fee, not delivering and no sign of improvement.
But you cant fault him for the rest of his signings.
Enrique, Adam, Bellamy, Suarez, Coates and Henderson have been good signings. Hendo has shown enough in my eyes to justify the signing, he'll become a great player for us. And I feel his current transfer dealings leave him with more good than bad.
The Carroll transfer will always haunt him though. As clearly we hadnt done our homework and even though we had scouted him it reeked of panic buy. Torres put us in that position, but that we didnt think about signing a player similar to Torres or someone more proven is mind boggeling. At least at that price.
Rafa signed some very good players, but also signed some absolute plonkers.
Degen, Voronin, Aqua, Keane, Dossena, Josemi, Morientes, Jovanovic (to a degree). Probably more aswell if you bother through the list.
