I think somebody else said it best with this.
January is about filling gaps.
Summer is about building the squad and setting direction.
Yes, a permanent would have been great, but it seems that there are many teams looking for left footed players. We got 2 (albeit 1 on loan). I think the summer could be tricky. Liverpool, Man U & a few others are also looking for LWBs (Man U were linked to Mitchell earlier in the window). Diouf looks a great prospect, but teams are now alert to him. However, you do have to ask yourself the question that if he was worth £20m surely other teams would have submitted bids too, but we were the only ones. I'm not saying he's not a good player. I'm saying he's probably not worth £20m. Plus, we were mainly looking for backup to Mitchell this window, so prospective signings will be aware of that.
We're playing well now (best away defence in the league) and have injured players like Wharton coming back into the fold. I agree we are light in CB, but we do have options (like Lerma & Clyne) if desperate. I think unfortunately, teams like Forest and Bournemouth have caught the league by surprise so other fans are thinking "why couldn't we have done that this year". Our reason was our start with an unsettled first team! If we had picked up 9-10 more pts in the 10 games of the season (which was achievable), we'd be top 8, so we're not far off. Injuries have hampered us hugely. Yes, we should have signed cover for the wing-backs, but we have purchased many players. There was no way of knowing at the beginning of the season that Wharton & Riad would have been as injured as they were. I also think there was optimism that Doucoure & Franca would feature more. Plus, no-one thought Kamala & Nketiah would be as bad as they have been.
Let's take the positives and have a great second half to the season. Wharton seems to be back. Sarr & Lacroix have been great signings now that they have settled. Esse looks a great buy to come of the bench and change games & Franca maybe back (maybe...). We're building a good squad now. We all know our first team would give any team a game, so it's just the bench options that we needed strengthen and that is starting to now look better.
I've noticed that the atmosphere in Selhurst is not as positive or raucous as it used to be. Yes, that is not usual for the amount of time we've been in the Premier League, but we need to get behind the team and especially this manager. He is probably the best manager we've had (potentially), so let's get behind him, show appreciation and make sure he enjoys being here so he doesn't leave.
