Its vital Sigurdsson plays in that number 10 role, where he has been so effective all season - the Icelandic worldwide has eight goals and 11 assists in 32 Premier League games so far this season, and if he is to add to that total its essential he plays in that attacking midfield role where he is able to dictate play.
Swansea City must add an element of feistiness to their game if they are to kick-start their bid to avoid relegation from the Premier League at Watford on Saturday, winger Wayne Routledge has said.
Clement's side have now picked up just a single point from the last five league games, dropping into the relegation zone with just six games remaining.
Midtable Watford moved onto 40 points, all-but-securing its survival in the top flight.
Ideally, Swansea should have obtained three points against Middlesbrough as well as getting something from fellow strugglers West Ham and Bournemouth, but the fact is they never. "But I don't know what the situation will be in three or four games". Now in 10th, a top-half finish could yet be achieved for a team who have lit up the division so little that it has nearly gone unnoticed that Mazzarri has settled in well.
"I thought there was an anxiety in our play and it's hard to say why that was the case".
"You look at some of the results and performances we have had, like winning at Anfield, that was a long way off that level".
In bright sunshine, Swansea had more than their fair share of possession in the second half but created little, their best chance a stoppage-time header by Gylfi Sigurdsson that flashed just wide. But I have always said to the players that if they are going to do that, they should not get too excited when people are praising them and they should not get down when they are being criticised.
A late surge at the end of 2015/16 saw them to safety, and it appeared an earlier one this season - with victories against Liverpool and Southampton to name but two - would prove similarly fruitful.
Both teams were threatening inside the final third, but the next clear chance came through a Niang free kick, although he was again denied by Fabianski.
