A spectator in the first half. Came off his line quickly twice in the second half to thwart a couple of Chelsea counterattacks.
A bit of a mixed bag as he linked well with Stocker down the left for Yakin's side, but he also made some clumsy tackles that resulted in free kicks for Chelsea.
He led the home side's defense well and started a number of attacks for his side with some searching driven passes from center back, one of which set up Salah for his goal.
Produced a disciplined display at fullback and showed his versatility by switching from the right to the left following the introduction of Ajeti.
Looked calm and composed at the back for the hosts, until the arrival of Torres and Hazard slightly ruffled his feathers.
Mohamed El Nenny
A decent all-round display in midfield from the young Egyptian.
Drove at the Chelsea defense with confidence from both flanks but will have been fairly peeved by his wastefulness from set pieces, particularly one well-positioned free kick.
Superb on the ball for his side. His movement was top notch and his one-touch passing really tested the likes of Mikel and Lampard.
G. Serey Die
The imposing midfielder excelled in a holding role in front of the back four which allowed Basel's more attacking players to flourish.
The exciting attacker looked menacing for the home side whenever he was allowed time on the ball and he proved the difference late on by scoring a fine individual effort.
Forced Cech into making a smart stop with a shot from 20 yards early in the game and held the ball up well for his side before being withdrawn late on.
Pulled off some fine stops in the first half to keep out Streller and Salah and could do nothing about the latter's fine finish late on.
The usually reliable defender looked out of sorts tonight against the vibrant attacking threat that Basel posed. Lost the run of Salah on the game's only goal.
The English center back was strong in the air alongside Terry but struggled when Basel attacked with the ball on the floor.
Found himself caught out of position far too often on the left for the Blues and produced some wayward passes over the course of the game.
Put in some fine last-ditch challenges, as only he can. Nullified the threat of Streller well in the second half.
J. Obi Mikel
The Nigeria international is normally so composed in possession, but he was guilty of misplacing a number of passes this evening. An under-par performance.
The Brazilian flashed in and out of the game during his time on the pitch, before being withdrawn late on.
One of his side's brighter performers in a fairly dismal first half, but then faded after the break and picked up a ridiculous yellow card for a foul on Die.
Looked off the pace in central midfield up against the athletic pairing of Die and El Nenny.
Anonymous in the first half as Basel doubled up on him whenever the ball went near him, and did not last long in the second as he was replaced by Hazard on 55 minutes.
Posed little threat during his time on the pitch before being withdrawn through injury just before halftime.
The Belgium international gave his side a brief lift with some clever touches and linked well with Torres.
K. De Bruyne
Had no time to stamp his mark on the game as a late substitute.
Replaced Eto'o shortly before the break and looked far more lively than the Cameroon international. Combined well with Hazard after the break.
