Steve McClaren admits he is uncertain if Newcastle United will bring any more players in this summer.

The Magpies have landed Dutch midfielder Georginio Wijnaldum, Serbian striker Aleksandar Mitrovic and Congolese defender Chancel Mbema, subject to a visa, which could be enough additions to the squad McClaren inherited from Alan Pardew and John Carver.

"Gini getting a couple of goals in the two games that he's played, showing his quality and that's what we've got in Mitrovic and Mbemba. That's what the club promised at the end of last season and the club have delivered on three very good players," McClaren told Sky Sports News HQ.

"I don't know (if there will be more to come). As I said before, we've got to be patient, they've got to be the right players.

"I'm happy with the players that we've got here, I'm happy with the additions."
