Is Mourinho building us a young team?

All the players you mentioned will be 30 is 8 years ffs. Too old!
 
Agreed.
I think he's looking at the future and trying to build a core - Lukaku, Pogba, Matic, Bailly, Lindelof, De Gea, even Lingard and McTominay. Looking at Fred and Dalot - young players, who are meant to replace aging player and hopefully it would be easy for them to bond with the afoementioned.
I so hope his ideas work out.

.......................Lukaku
LF/LW................................... Lingard
...............Pogba...............Fred
................... McTominay
LB.....Lindelof ..............Bailly.......Dalot
.......................De Gea

Don't know if the weed's speaking or me, but I think in 5 years time, this will be our team.

Chuck Fosu, O'Connor, Greenwood and Chong in there for
 
Maybe it is pressure from the board to sign younger players, with a sell on value.
