Ole Gunnar Solskjaer says Manchester United are working on improving their squad for next season, but he refused to comment on Jadon Sancho.
The Red Devils have finished trophy-less for the third consecutive season after losing 2-1 to Sevilla in the Europa League semi-final on Sunday.
Speaking to BT Sport, Solskjaer said: "We are working to improve what we have. We've had spells with injuries. We're always looking to improve the squad.
"It's not about a marquee signing, it's about quality. The right personality that fits into the group."
On the rumours surrounding Borussia Dortmund winger Sancho, Solskjaer added: "I'm not commenting on other teams' players."
