Alex McLeish hailed his Birmingham side after they stunned League Cup winners Tottenham Hotspur 4-1 and also eased their relegation fears. A Mikael Forssell hat-trick and a fine free kick from Sebastian Larsson secured a vital three points as City brought Spur's Wembley heroes back down to earth. City boss Alex McLeish, who took over the St Andrews side when he quit his job as Scotland boss at the end of November, feels his side is gradually taking shape. 'We defended well and deserved our half-time lead and were pleased at the break,' he told the BBC website. 'The chances kept on coming and Mikael Forssell deserved his hat-trick. Recently we have been working hard on free kicks in training and it was great to see one finally go in. We just have to keep on going now and concentrate on our own performances and try and pull out of trouble.' Spurs boss Juande Ramos made sweeping changes to the team that beat Chelsea in last Sunday's League Cup final. Central defenders Jonathan Woodgate and Ledley King dropped out through injury and they were replaced by Younes Kaboul and Didier Zakora. Tottenham assistant manger Gus Poyet believes that their under-strength side didn't really get going. 'Making so many changes were no excuse, the players who came in had a chance to show what they can do,' he said. 'Paul Robinson had a difficult day but he pulled off some good saves. We didn't wake up after the first goal, and we didn't perform. 'But we have to be strong mentally and be better than we were today which frankly wasn't good enough.' Spurs looked shaky at the back and it was no surprise to see Birmingham take the lead with the first attack of the game in seven minutes. Liam Ridgewell was allowed a free header from Gary McSheffrey's corner and the unmarked James McFadden squared to Forssell (pictured), who headed past Robinson. Robinson was at fault for Birmingham's second after 55 minutes. Larsson scored it, curling a right-footed free kick over the Spurs wall and into the corner of the net. With Spurs in disarray at the back, Birmingham took further advantage scoring their third goal a couple of minutes later. Pascal Chimbonda almost volleyed into his own net and although Robinson kept the ball out, it fell to Forssell, who side-footed home. Forssell secured his hat-trick beating Robinson after finding himself one-on-one with the Tottenham keeper thanks to McFadden's through ball in the 81st minute. Jermaine Jenas scored a last-gasp goal for Spurs but it didn't take the shine off a terrific performance from City.
