Could the Colombian's arrival push the versatile Tottenham star away from a first choice role.

News that Tottenham Hotspur's first signing of the summer is to be Ajax's Davinson Sanchez is strange indeed when you look at the fee reported. A figure as high as £42 million has been mentioned by the likes of the Guardian, blowing the club's existing transfer record out of the water.
It perhaps indicates a willingness for Tottenham to commit to three central defenders at the back this season, with both Toby Alderweireld and Jan Vertonghen vital to Mauricio Pochettino's gameplay.
But where will such a high-profile, expensive switch leave the man who featured as the third in a back three last season - Eric Dier?
The England international is understood to be a big favourite of Pochettino, but has been shunted all over the pitch during his stay with the north Londoners. Despite have impressed in defensive midfield in the 2015/16 season, Spurs brought in Victor Wanyama from Southampton last summer as competition for Dier, and the Kenyan shone in the role. Dier is second choice in that position, but saw plenty of football in defence as Spurs switched to 3-4-3 for much of the campaign.

And now it is possible that Sanchez could secure that role from him in much the same way as Wanyama did last season.
Of course Tottenham are improving the quality in the squad by bringing in the reigning Ajax Player of the Year. All attached to the club want more options to come in in what will be a busy schedule this season, and if Sanchez justifies his fee, and the likes of Dier raise their game in light of the added competition, the club will be better off because of it.
But it is unlikely that such a fee will be spent on the Colombian for him to merely have Kevin Wimmer's role - that of a firm backup option - so Dier could find another of his routes to becoming first choice in a position in jeopardy once again. At the very least, it suggests there will be much more rotation in central defence this season, and possibly, fewer opportunities for the former Sporting man.
