You know that bit, I can understand. Felt the same for a while initially myself, re leaving on a high etc.
But, the landscape is completely different now. And in the context of all things considered, it is a brilliant move.
If he had signed that extension, he would still be here this season, so it is almost like adding Kovacic now.
We need a body in midfield, we need cover for a couple positions, we have been unable to sign anyone in this market.
We need to spread Alvarez's minutes he played in midfield and Gundo is a better player in that position without doubt.
He cost nothing, he is on a year's deal.
Knows the club, no adjustment period.
Will be hungry as fuck, having been frustrated at Barcelona and having missed out on 4 trophies here in that time.
We have ample space in the squad, 3 slots once Cancelo leaves, so he isn't pushing anyone out, or stopping us signing a forward.
Gives the youngsters time to develop rather than being crippled by expectation, and they can learn from him.
And that's not even touching the future potential manager theory, which I think is a long way away.
