Newcastle United hero Les Ferdinand has been impressed by their market work this summer.
However, Ferdinand feels they must be wary of the mistakes made at Tottenham last summer.
"You look at the players Newcastle have brought in and you'd say it's been a very good summer and I can see why fans might be excited again,' he said. 'I have been to watch Siem de Jong play for Ajax a few times and he is a top player.
"It will be interesting to see how that translates to the Premier League because I thought he was very good in Holland.
"But I was at Spurs last year and we spent a lot of money on new signings and everyone expected us to challenge for the league.
"It didn't happen that way and you'll probably find Spurs come back better this season for those lads having had a year to settle in.
"That could be the same at Newcastle, but has the manager got that time?"
