45' + 3' HALF TIME: Sheffield United 2-0 Chelsea
45' + 2' James chips in a dangerous cross towards Pulisic at the back post that Basham does well to glance away for a corner that comes to nothing.
45' + 1' Two minutes of stoppage time are added.
44' James lashes a vicious shot from 25 yards that Henderson safely palms away from any onrushing Chelsea attacker.
43' Sheffield Utd quickly move forward on the counter-attack after McBurnie holds it up well, but Stevens' pass is cut out by Zouma and Chelsea rebuild from the back again.
41' Chelsea have looked disjointed following the second goal, and another move breaks down as Mount overhits a pass towards Pulisic and it drifts away for a throw-in to the hosts.
39' Pulisic tries to revive his side by dinking a deft cross towards the back post, but Abraham can't quite stretch to reach it and the hosts clear again.
37' Abraham attempts to scurry past Egan on the break, but the defender manages to hold him off before clearing it upfield.
35' Well, this has been a fantastic half from Sheffield United so far! They've restricted Chelsea's attack with their deep defence and then in possession they've peppered their box with accurate pressurising crosses - they're well worth their two-goal lead currently!
32' Norwood attempts a simple header back to O'Connell but he overpowers it and - for a moment - it looks as though Willian might latch onto it, but the defender recovers and backtracks to clear.
30' Another Chelsea move ends limply with a Barkley cross that Basham hooks comfortably away from harm.
28' Out of possession, the hosts are dropping into a notably deep and structured shape to try and restrict this goal-hungry Chelsea side.
26' Chelsea search intently for an equaliser with a long spell of possession in the Sheffield Utd half, but they can't find an opening and McBurnie manages to clear.
24' The match is paused for a brief drinks break.
22' That effort was McGoldrick's first Premier League goal of the season after 25 appearances! The striker will be delighted to have opened his account and especially pleased that it arrived at such a crucial moment.
20' The hosts will be thrilled with this start! They've launched crosses into the box at every opportunity in the opening 20 minutes and they get their reward as Baldock's delivery is forced in, after Kepa had made a strong save from McBurnie's volley.
16' The away side methodically move forward again after a neat combination between Barkley and Mount, before Willian takes over on the right-wing where he slices a cross away for a goal kick. Nevertheless, Chelsea will be pleased that they're beginning to control the pace of the game now.
14' Chelsea quickly spread play out towards Pulisic on the left flank and he beats Baldock before McGoldrick energetically tracks back to tackle him just inside the box. The hosts will need to replicate that energy throughout the game to hold off Chelsea today.
12' Christensen is down after an awkward fall under little pressure, but after a brief pause for treatment, it looks as though he'll be able to continue.
10' Both sides have started brightly so far, in an open first 10 minutes. The hosts have enjoyed plenty of possession and they've looked to put crosses into the box at every opportunity, but Chelsea have looked threatening when they've been allowed to counter-attack.
8' Pulisic goes close for Chelsea! James finds a pocket of space on the right flank and he proceeds to swing in an inviting cross that drifts to the back post where Pulisic dives in to nod a header from close ranger a few yards over the bar!
7' The hosts force another corner and Chelsea fail to clear their lines before Osborn relieves the pressure by blasting a wild shot over from 20 yards,
6' The hosts have been tight and well organised defensively this season and they owe a lot of their success to this. Today, however, will be a huge test for their suffocating backline: they face a Chelsea attack that has scored at least twice in each of their last eight Premier League games!
4' Barkley drives into the Sheffield Utd half and fires a tepid shot from 25 yards that trickles safely into Henderson's grasp.
2' The hosts immediately pump it forwards from kick off and Stevens latches onto a flick-on from McBurnie before having a cross deflected behind for a corner. However, Kepa skillfully punches the delivery away from harm and Chelsea clear.
1' Sheffield United get the first half underway.
The players are emerging from the tunnel and kick off is just seconds away!
