The Welsh side's manager has praised the way Spurs have dealt with the departure of Gareth Bale, signing seven new players, and believes the north Londoners will pose a stern test
The 41-year-old has seen his team pick up back-to-back draws in the Premier League after a shock win over Manchester City, but has acknowledged that Tottenham will pose a different threat.

"The players they brought in everyone in football knew they were top talents," the Cardiff boss told reporters.
"We knew they were on the market but would cost a lot of money. Again, though, because of the extraordinary amount they brought in from the Bale deal meant they could do it.
"The squad looks like a Champions League squad. They are in that bracket [with Manchester United, Manchester City and Chelsea].
"They have a squad full of quality. I have no doubt that we will be facing a team up for it and packed full of quality.
"They have bought very well. They had a real match winner in Bale. He has that quality. He left a huge hole but they filled it well. The extraordinary size of that fee let them bring in seven or eight quality players. It has changed Tottenham."
