I disagree, Trippier would be astute signing....Teams actually allow AWB to have the ball as they know he offers little idea going forward. Do i think he has improved, yes, i do, but still not good enough... Tripper gives us options in both full back positions, can cross a ball and defend well. Last year AWB was overplayed towards the end of the season he was running on empty and positionally i still think he is suspect, at very worst Trippier will provide cover and competition , if available for 15mill its a no brainer.
You mention Telles and Shaw...look how well Shaw has performed since Telles came in.... competition for places is a good thing, we need strength in depth and Trippier is an upgrade on Dalot and Williams
