I honestly think Pérez just likes doing things, so he invents problems fix every summer.
Clement has certainly had quite a career in coaching thus far, will be interesting to see if he can step it up to management. Think they should have stuck with McClaren though, if he was happy to stay, 1 point off the playoffs whilst dealing with a lot of injuries really isn't that bad in a season like this.
Karanka's objective this summer is obviously to get the team scoring more goals. When I've seen Boro this season it has often been Vossen in behind the main striker, it hasn't always been effective, so a real attacking midfielder should be signed. Tomlin seems to unbalance the side somewhat so I guess maybe sacrificing him wouldn't be too bad long term, although only if that attacking midfielder is found. As for strikers I wonder if Neil offered him Becchio or Lafferty after the game yesterday.
Now the season as finished and loans have returned our strikeforce looks like this - Jerome, Grabban, Hooper, Becchio, Lafferty, van Wolfswinkel, Loza and Morris. Considering the fact we'll almost certainly use 1 striker formations next season it's safe to say that is a little crowded.
