Wolves boss Julen Lopetegui admits they need to buy in January.

The newly hired manager has used the World Cup break to assess his squad.

The Spaniard said: “We have to be very clear that the main actors are here, they are here, but after, I don't know what's going to happen. Of course, we want to improve our squad, we need to improve our squad, we have to be competitive.

“At the same time, we have to increase the confidence and the players have to believe in themselves, to show they are better players than they have shown at the moment, and they have to do their all to change the situation.

"We can help them, but the key moment is the players' determination and commitment to change the situation."
