Chelsea hero Pat Nevin says Saul Niguez will prove himself a canny addition.
The on-loan Atletico Madrid midfielder has had a slow start to his time with Chelsea, but Nevin can see Saul proving his value over the season.
Speaking to Chelsea's official website, Nevin said: "Another thing that becomes clear now is that the recruitment of Saul also makes more sense when you want to play three in the central midfield area and they have to play at a ruinously high tempo.
"They must get rest games in this style, so another midfielder is good planning.
"I think the slight doubt over the weekend's tactics (against Manchester City) was a bit early. This could be the direction we take longer term, and certainly in at least some games going forward."
