So why the clamour for Grealish. If stats don't matter and age is of the utmost importance, why should we sign Grealish.
And if stats don't matter, why do you constantly use them?
Because he's a great player. I think it's highly likely Pochettino makes more out of a Grealish than he would out of a Norwood.
Stats DO matter when used in the correct context. A bit like when people say Sissoko is good defensively, even when the stats prove that he isn't or when people say Winks never passes forward despite stats showing you that he makes more successful forward passes than anyone on our team (and more than he makes sideways or backwards)
But then you have to take into consideration the teams they play for, how important they are to their team, the style of play their teams play for etc. - when comparing players like this who aren't particularly KNOWN for assists or goals, it's best to look at their impact to the team.
Also how their assists or goals come about. Norwood is Sheffield Uniteds penalty taker, so his goals are coming via penalties. I believe he also takes their set pieces. Grealish doesn't take set pieces for Villa nor does he take their penalties. He's more of an assist the assister (a bit like Dembele)
Norwood is a good busy player and there are PLENTY of those about in the lower leagues and the lower end of the Premier League, probably a big reason why he's not played a single second of Premier League football in his 10 year career.
Hard to compare their importance to the team when it comes to Norwood as he's played every single game this season in the league. Last season however, he missed 10 league games, Sheffield United won 7 of them, drew 2 of them and lost just 1 game.
Grealish however, was severely missed, which probably shows how important his overall play is to the team. he missed 13 games through injury and they won 2 games. Since he's come back from injury, they've made up 6 points in the play off place, they've won all 4 games and he's scored 2 goals and got 1 assist within that time with one being the winning goal in a derby.
In fact after a slow start to the season, his stats from his last 10 league games are:
Played 10
Scored: 4
Assisted: 4
Won: 8
Drawn: 2
Lost: 0
There's a player there with untapped potential.
