The Telegraph reports that the transfer fee is £3.5m, and Sky is reporting that Trippier is scheduled to have a medical with Spurs within the next three days. Assuming personal terms are agreed, the deal might be completed by early next week and would go through when the transfer window opens on Wednesday, July 1.
Trippier is a solid right back option, and would give Spurs both a good amount of competition and an insurance policy for Kyle Walker, who has struggled with injury over the past few seasons. As Michael Caley wrote yesterday, this signing should be considered Tottenham hedging their bets against the possibility that Walker never regains the pace and fitness that made him one of the better right backs in the leagues a few seasons ago. Trippier had a good season for the Clarets, starting all 38 league matches for Burnley and tallying three assists.
Trippier would be Spurs' second signing of the offseason after central defender Kevin Wimmer. He would be a very solid rotation option and could easily step in and deputize or supplant Walker if needed, allowing DeAndre Yedlin to ease his way into the club via cups and Europa League appearances. This also means that we'd be seeing a lot more actual right backs playing right back and less Eric Dier playing out of position, and that in itself is a really good thing.
