We're going to Wembley! Didier Drogba's third goal in four games and Alex's counter-attack strike have put Chelsea into the FA Cup semi-finals.

Comfortable is the word to describe this win in front of a record 31,407. Coventry had their odd moment but marshalled by another superb John Terry display, the defence never looked likely to be breached.

At the other end, Drogba's opener came early and the second added midway through the second half, just as the home team were working up a head of steam.

There was also the bonus of Michael Essien successfully negotiating the final 30 minutes of the game. He had been joined on the bench at the start by an also-returning Ricardo Carvalho.

By his team selection for his FA Cup 'debut', it was clear Guus Hiddink was taking the competition seriously. He named an unchanged 11 from the win at Portsmouth and there was nothing in the opening to the game to suggest the players weren't taking it seriously either.

Drogba could have put Chelsea ahead as early as the second minute. The chance was created by his own skill, as Coventry centre-back and captain Dann stood off tentatively but having worked the space, our centre-forward shot wide.

Lampard, Kalou and Ballack combined for a shot over by the German as the visitors continued to look dangerous on the attack.

The opening goal came as early as the 14^th minute. With every ball forward, it didn't appear the Coventry defence knew the best way to handle Drogba so it was no surprise when the central defence were caught standing and staring as the Ivorian picked up a long ball.

Through on goal he touched it away from keeper Westwood and with defenders racing for the goal, Drogba was calmness itself as he smashed home from an angle.

Terry was well-positioned to clear a shot from Eastwood as the home side attempted a quick response. Coventry did genuinely worry Chelsea 24 minutes in as the nippy Leon Best won a tackle ahead of Alex and cut inside Terry but hurriedly shot over.

On 30 minutes, Lampard and Bosingwa combined to set up a Ballack shot but Turner blocked bravely.

There was a good tempo to Chelsea's passing, as there had been from the start with Hiddink's men working it out well from tight corners at the back.

On 35 minutes, Coventry carelessly conceded a free-kick for a foul on Cole, predictably jeered at every touch by the home support. Westwood between the Sky Blues' posts is by no means the tallest keeper but he did well to finger tip over Lampard's deadball strike that was arrowed towards the top corner.

To close the first half for Chelsea, Drogba smashed a low 25-yard shot wide after some brilliant Lampard footwork had carved open space and Kalou did similar from closer range after a Malouda cross.

There had been plenty to admire about Chelsea's attitude and approach play in the opening period, but just the nagging thought that more goals should have been on the scoreboard.

Hiddink made a half-time substitution, Quaresma a straight swap on the right for Kalou whose first-half decision making had been questionable.

No doubt having been on the end of a half-time rallying call from their manager Chris Coleman, Coventry made it more of an even contest in the first 15 minutes after the break with little in the way of penalty area action. Quaresma was proving adept a drawing fouls from the home side out wide.

Hiddink sent for the Bison. Michael Essien made his return after six months out in the 64^th minute, coming on to huge applause from the 5,000 Chelsea fans and as a replacement for Mikel.

The home side enjoyed a good couple of minutes shortly after, Cech pushing away a cross and Alex blocking a follow-up shot before a Gunnarsson long throw fell between Eastwood and Best as it was flicked on. Neither was able to make the crucial contact.

On 70 minutes there was a painful clash of heads between Alex and Drogba as they defended the same set-piece. The result was both players off the field for another long throw.

Chelsea survived thanks to a towering Ballack header. In fact we did rather better than that! In a flash the ball was in the Coventry net, Malouda starting the break and Quaresma taking up the baton before crossing low to Alex of all people to drill home at the far post. The smash on the skull had done the Brazilian no harm at all! There were 18 minutes left to play.

Lampard could have made it three on 78 minutes but he couldn't poke Malouda's pass beyond Westwood.

Morrison didn't make the most of a moment's hesitation between Cech and Alex and Gunnarsson shot ambitiously and wide as Coventry attempted to respond.

Lampard tested the keeper once more with a free-kick before Terry completed his own exemplary display by blocking a dangerous cross and then throwing his whole body into an aerial battle. The clean sheet, a fourth in five games under Hiddink, was assured.
