We certainly have stocked up on a lot of defenders under Poch...
Have we though?
Under Pochettino we have seen Assou-Ekotto leave and Davies come in.
In central defence, Pochettino's time at the club has (or is likely to by the end of this window) seen go:
Dawson, Kaboul and Chiriches.
And brought in:
Wimmer, Dier, Alderweireld and Fazio
On the right we've seen the departure of Naughton. With Trippier and Yedlin coming in.
So we've added two players to our back four, and I would argue we were probably two players light in defence when he arrived (one factor - of several - in our poor defensive record last season IMO). It might seem like "stocking up on defenders" because we've had three arrivals in the first week of the window and they are all in defence; but it's really not.
What's more, I'd go so far as to say that Pochettino has not only plugged some holes in defence, he has also upgraded almost universally...
The Dier of next season is going to be a big improvement on whatever Kaboul is capable of. And he'll be even better the following season. I'm 100% convinced of that.
The jury is out on Yedlin (and he may even end up on loan this season if you believe some reports), but by most accounts Trippier is an upgrade on Naughton. He might not work out of course (always a risk) but it's hard to argue we've done bad business there.
It seems likely that Assou-Ekotto had effectively burnt his bridges with the club by the time Pochettino arrived. So his hand was forced there. Based on his first season, it's hard to argue Davies was an upgrade on BAE
at his best. But it's equally hard to argue that we were ever going to see BAE at his best again. Overall I still think Davies has a decent future at Spurs. And going into the season with him as our second choice... as back-up / rotation for an on-form Rose, we could do a lot worse. (And have done!)
I loved Dawson, and it was a sad day when he left the club. But I suspect that the Alderweireld of 2015 is going to be an upgrade on the Dawson of 2015. I think we may have done very good business bringing in this guy. Looking forward to
not being proved wrong in my optimism this season!
Which leaves a two-for-one swap... Fazio + Wimmer for Chiriches?
In my view, that's an upgrade too. So we have certainly overhauled our defence under Pochettino; but I'd argue our defence was ripe for it. And far from stocking up on defenders, we've merely brought the number up to roughly the right number.
