That policy won't bring us anywhere. Once these youngsters established themselves, they will try to move to big clubs who can win trophies. I think we already have too many youngsters at Spurs. We need more experienced players to help us fight for honours. I find it hard to believe that we cannot sign more experienced players in the mould of VDV, Vertonghen, Eriksen, Chadli, Modric and Berbatov. They were well established and well-known players when we bought them. I think it is pointless to buy those unknown players from small clubs like Wimmer, Trippier and Yedlin who will struggle at big clubs like Spurs.
Come on man. How much hindsight and confirmation bias can you pack into one post. Eriksen, Chadli and Modric were all either at a similar age to Trippier or younger when we signed them. Apart from VdV and (to an extent) Berbatov all were unproven outside the big leagues and pretty clear gambles.
Trippier is a more experienced cover at right back than Dier and Yedlin. He's fairly experienced at 24 (25 in September) with a full PL season behind him and 5 full seasons in the Championship under his belt. At a very reasonable cost he's at worst a useful squad player.
We need a mix between youth and experience. A PL proven, cheap, good player in a trouble position for us is a solid signing in that regard. Our back 5 (defenders and GK) isn't currently extremely young with Rose, Verts, Fazio and Walker all in their mid-late twenties. We have some very talented young right sided full backs in Yedlin and Walker-Peters. We have an established, but perhaps injury prone, first choice right back. So we bring in a PL proven option to at best compete with Walker, but at least give us good cover while we wait for the youngsters to develop. Seems like smart squad management to me.
He's an attacking fullback, if he held back more, he would not be providing an outlet in attack.
I think that Walker, on form, is a better fullback than Rose.
I think Walker being "an attacking fullback" is a bit of a misnomer. When he's been at his best he's been much better defensively. In form he's almost impossible to get past with his pace and power, and his positioning has improved significantly since his initial season (and a bit). He gets back against counter attacks very quickly and consistently and he can bail out a slower central defender.
When attacking he lets us down way too often though. His crossing and end product isn't up to standard and even his passing is at best average. Often one of the worst passers in our team imo. He gets forward a lot, he has tons of energy and will always be a threat with his pace. He can help create space for others, and he can of course contribute (he's obviously not brick), but he's clearly limited on the ball.
If I had to pick one player for a game where we had to do more defending, and one player for when we have to do more attacking I would pick Walker for the former and Trippier the latter. Trippier gives us a quite different option to Walker in that regard. Someone with a genuinely good cross to support what will most of the time be an "inverted winger". Seems like a good option to have, might even be used as an impact player off the bench similarly to Kolarov at City etc.
