Kris Commons marked his return from injury with a double to help Celtic to a comfortable 4-0 win over Hamilton Academical that took them clear at the top of the Scottish Premiership on Sunday.

A well-organised Hamilton defence frustrated Celtic in the first half with Swedish striker John Guidetti guilty of missing a host of chances.

The breakthrough came in the 57th minute through Commons before Stefan Johansen tapped in a second.

Guidetti finally got on the scoresheet with a 78th-minute header before Commons made it 4-0 two minutes later as Celtic extended their unbeaten run to 11 matches ahead of Thursday's Europa League return with Internazionale in Milan.

The win moves the Hoops three points clear at the top of the Premiership ahead of their clash with nearest rivals Aberdeen next weekend.

Following their exertions in the 3-3 draw with Inte on Thursday, manager Ronny Deila made four changes to his side as James Forrest, Guidetti, Efe Ambrose and Commons all landed places in the starting line-up.

Swedish striker Guidetti, who scored a stoppage-time equaliser against Inter, came close with an eighth-minute header from a Commons cross that 'keeper Michael McGovern saved on the line.

The Hamilton stopper came to their rescue again three minutes later when he got down low to block Guidetti's snapshot as he connected with an Ambrose cross.

Hamilton defender Michael Devlin then put in a superb challenge to stop Guidetti in his tracks as he delayed hitting his shot after a good headed knockdown by Ambrose.

Commons laid the ball on a plate for the Swedish striker after good work down the right but he failed to make a clean connection with his effort and it rolled straight to McGovern.

Johansen was then off-target with a header as he got on the end of Emilio Izaguirre's cross as Celtic's finishing continued to let them down.

The home side's frustrations grew at the start of the second half until Commons broke the deadlock in the 57th minute.

The Hamilton defence split as Virgil van Dijk surged forward from defence and his pass took a touch off substitute Darren Lyon, who had been on the pitch for a matter of seconds, before reaching Commons who lashed a volley beyond McGovern.

Moments later Johansen connected with a floated pass over the top but his weak strike was straight at McGovern.

Scott Brown then fed Guidetti in the box but the striker was foiled by McGovern who got down low to block his dinked effort.

Johansen, who hit the post with a drilled shot in the 63rd minute, went one better a minute later as he made it 2-0. McGovern failed to hold a stinging strike from van Dijk and spilled the ball at the feet of Johansen, who had the simple task of tapping home.

McGovern made a tremendous double save from van Dijk and then Adam Matthews before Guidetti added a third as he rose to head Izaguirre's cross home from close range in the 78th minute.

Commons completed the scoring two minutes later. Van Dijk again caused the Hamilton defence problems with a rampaging run and Commons applied the finishing touch to the Dutch defender's pass.
