Let’s put this into the right context. That passage is after this passage:
Then subsequently, a while after, when it became apparent that Trippier was now getting preferential rotation (where previously that had always been Walker), you get the passage you quote.
I believe Walker knew ManC and probably ManU we’re interested in him already. But that goes for most of our players. But I don’t think he’d have thrown his little tantrum and gone about it like he did, if his nose hadn’t been put out of joint by Poch deciding to give Trippier more games.
I’ve never said it’s black and white, but it’s clear that Walker marching in and saying he wants to leave was definitely after Poch had started to play Trippier more, and for the weekend games, not just as “number 2 back up”. Whereas many seem to think it was the other way round. Now even Walker has pretty much corroborated this version of events.
I don’t blame Walker at all, in his situation I’d have done the same. Be rotation on less money or be first choice on more money at City? But I don’t think he’d have jumped - especially in the “toys out of pram” way that he did, or been allowed to go (as we had him on a long deal and blocked others like Dier and Rose) if Trippier hadn’t established himself as Poch’s first choice or at least equal choice.
