Manchester United legend Denis Irwin is impressed by Jose Mourinho's market work.
Irwin thinks it has been a summer of good business in a transfer window of 'eye-opening' amounts spent on players.
Defender Victor Lindelof, striker Romelu Lukaku and midfielder Nemanja Matic have all been snapped up by Mourinho.
"Lindelof will take a bit of time but will turn into a very good player," Irwin said.
"Lukaku and Matic are good additions. Matic is a really experienced, solid performer."
But Irwin feels United will have a fight on their hands, as others battle it out at the top of the league. He thinks reigning champions Chelsea may find it harder this season, along with Tottenham.
"Chelsea have got European football and Spurs are now at Wembley," he said.
"Manchester City will be strong this year and Arsenal have bought a striker which was needed. I wouldn't dismiss Everton. It's going to be a very competitive league I think."
