There was report on us being interested in Pepe on a free. I would be totally for that move. Karius can learn a lot from him, and he will be a steady hand who we can bank on when needed. We wouldn't go too wrong with this decision.
That would leave our budget in tact for more pressing needs.
Hopefully we stick to what has worked for us in the last two season quality over quantity. Focus efforts on bringing two signings (on top of Keita and hopefully Pepe) who have a high chance of working well for us.
This means we won't be changing too much. Our focussed efforts with good financial backing will allow us to continue in this path.
We are not City or Chelsea to address our squad depth issue in one season. No outgoing (except may be Ming, Moreno and one of Klavan or Lovren) and four top quality additions including Keita will absolutely do for us.
