Sheffield United boss Bryan Robson insists he is not feeling the heat despite only managing a 2-2 draw at bottom club Colchester.David Carney's goal earned the Blades a point at Layer Road after they had fallen behind to second-half strikes from Kevin Lisbie and a deflected Johnnie Jackson free-kick, following Luton Shelton's opener.

Robson said: "Things didn't go for us but there were a few good performances and I can't ask any more from my players.

"The players are right behind me and I don't feel under any pressure. We're not winning games that we deserve to win and we're not killing teams off when we have the chances to.

"It's a forward-thinking club and I'm sure that we can keep on getting better and better."

Colchester manager Geraint Williams said: "The game could have gone either way but I felt that if any team was going to win it, it would be us.

"I think some of the football we played was some of our best of the season.

"We showed a lot of confidence and belief and I was delighted to see the lads so positive.

"But we've been punished for a mistake again and that's what's been happening this season."

Colchester were dealt a body blow in first-half stoppage time.

After a Colchester corner had been cleared, Shelton muscled his way past Kem Izzet on the left and advanced on goal.

The Jamaica international went on to curl a precise shot past goalkeeper Dean Gerken to give his side the lead.

It was somewhat harsh on Colchester, who had looked bright and inventive.

Both sides had efforts cleared off the line in the first half.

Stephen Quinn had to be alert in order to nod Chris Coyne's goal-bound header away from danger, while Phil Ifil did the same for Colchester to deny Gary Speed.

Colchester needed just 24 seconds of the second half to get back on level terms.

Izzet's pass from midfield dissected the Blades defence and Lisbie finished emphatically into the top right-hand corner, leaving Paddy Kenny with no chance.

The Us were ahead in the 61st minute when substitute Scott Vernon was fouled by Chris Morgan on the edge of the area and Jackson's free-kick took a huge deflection off Jon Stead and went in.

However, their lead lasted barely two minutes, after Carney finished neatly on the turn after a free-kick had not been sufficiently cleared.
