Tottenham midfielder Gylfi Sigurdsson has welcomed their two new signings.
Paulinho and Nacer Chadli have both been signed this summer.
Sigurdsson said: "We saw Paulinho in the Confederations Cup, he looked a good player there and was shining.
"We've signed Nacer Chadli as well, who is looking really good in training. Hopefully we'll bring a couple more in.
"You never know how it's going to go, there could be a couple of other teams fighting for the title. There's going to be about six teams fighting up there - it's always tough, whatever year it is."
