I don't think there is much wrong with the purchases individually or collectively from his position. Last season I'd think it's be likely Walsh was responsible for signing Lookman, DCL, Gueye, this season I'd only say Onyekuru, but maybe Pickford or Keane, maybe identified Sandro, but Koeman certainly did the romancing if memory serves me correct. I think Rooney would have been unanimous, I look at Sigurdsson as more of a manager buy, given the eventual outlay, but think both probably wanted him.
There has been oversight in terms of the requirements. Our 2 main objectives in summer surely must have been replacing the 2 players who got the most goals and assists for us, 2 most central players to how we attacked. I think on paper we signed players who got more goals and assists last season, there just doesn't seem any logic about who is supposed to be doing what or how they fit together. That's more to do with the coaches domain, in terms of requesting certain types of players. We got virtually all the players we wanted and could get. If the manager was that worried about where the goals will come from, he had opportunity to make that a priority.
From our summer midfield signings, it's only really Vlasic who looks capable of running at opponents with the ball, think he'll become more central to our play because of necessity. But I also like DCL and I think he's been unlucky to not score a few and the supply has been pretty poor, compared to the level of service we gave Lukaku last year. I understand the logic in surrounding a striker with goal scoring midfielders, but we don't have the same presence up front, and I noticed increase in just aimless selfish hopeful shots from range. Whether it's desperation, lack of options or players competing against each other rather than working together, it's not a good habit.
In a world of Kevin Mirallas', Niasse is king.
But I think Walsh's remit is more about identifying players and making sure the business makes financial sense. It was Koeman's prerogative about what types of players he wanted, the priorities for the first team and how it fits together.
