Tottenham boss Harry Redknapp has hailed keeper Heurelho Gomes' turnaround in form at the club.
The keeper was suffering a lack of confidence when Redknapp took over at White Hart Lane in October last year, with the club sitting rock-bottom of the Premier League table.
Redknapp admits he had his doubts about the Brazilian but believes Gomes is now showing his true colours following his £7.8million switch from PSV Eindhoven.
The Spurs boss believes goalkeeping coach Tony Parks has helped the keeper to regain his confidence.
Redknapp said: "There was a time when I had my doubts about Gomes.
"When I first arrived at Tottenham, I thought 'we've got a problem here' because he was going through a bad time.
"Tony Parks coming has made a big difference. Tony had him working on the training ground while before he was looking at the technical side of it.
"The hard work has got into his head and given him the confidence he needed.
"When Gomes joined Tottenham, Tony Adams said to me that Spurs had signed the best keeper in the world. Tony had been working in Holland.
"Guus Hiddink, who had him at Eindhoven, was saying the same thing.
"I thought are they all right or what? Tony's not drinking any more... But now he looks a terrific keeper."
Gomes kept his third successive clean sheet in the Boxing Day goalless draw against Fulham, where he produced a string of fine saves as Spurs escaped Craven Cottage with a point.
Redknapp was pleased with the draw at Fulham, believing it is difficult to win anywhere in the top flight.
Next up for Redknapp is former club West Ham at White Hart Lane on Monday - in a game being shown live on Sky Sports 1 and Sky Sports HD1 at 12.45pm - and the Spurs boss is expecting another tough encounter as his side look to keep pressing for a top four finish.
Redknapp added: "It's a good point at Fulham - they beat Manchester United convincingly last weekend.
"I thought Chelsea would win, not draw, at Birmingham (yesterday). I also thought they'd go to West Ham and win, but it's so difficult at the moment.
"It's hard to get three points. Anyone can close the gap on Chelsea because they haven't been that convincing but they still have a nice lead.
"Other clubs have improved their squads and are having a go. Every game is more difficult.
"Smaller clubs are no longer rolling over for the bigger ones. It's hard to pick up results.
"But I still think we're good enough to finish in the top four. There won't be much between us and Aston Villa and it will be interesting to see how Manchester City go now.
"I think we've got a chance of breaking into the top four. I've told the players we can do it, let's have a go."
