Tottenham manager Harry Redknapp believes his side have developed a mental toughness as they bid for a top four slot.
Peter Crouch got both goals in the 2-0 victory against Blackburn at Ewood Park to keep the pressure on the leaders.
Redknapp said: "It was not a pretty game but one Tottenham may have lost in the past. It was a great result for us. It was a tough match but we have collected three points and kept a clean sheet away from home. I have to be pleased with that."
He continued: "It was not free-flowing football like it was in midweek against Manchester City. However we were solid at the back and the goalkeeper did well for us."
Crouch made the breakthrough in first-half stoppage-time when he headed home following a cross from Niko Kranjcar, who chased a lost cause before delivering the ball into the box.
Bolton manager Sam Allardyce, marking his first year in charge, rounded on referee Peter Walton for allowing the goal.
Allardyce said: "It is a foul on Ryan Nelsen. He has wrestled him to the floor and thrown his arms around him. The referee is in a good position but doesn't give it.
"We were also 90 seconds into injury-time and only one minute had been put up. So instead of being comfortable in the first half and coming in at 0-0 we have been let down by the referee once again.
"We do not like it when the referee messes up but there is little we can do about it."
