European round-up: Chelsea labour to first leg win over Servette, Larne narrowly beaten as Scots duo lose

Chelsea laboured to an unconvincing 2-0 win over Servette in the first leg of their Conference League play-off at Stamford Bridge, second-half goals from Christopher Nkunku and Noni Madueke sufficient to give Enzo Maresca's side the lead in the tie.

Irish Premiership champions Larne were beaten 2-1 by Lincoln Red Imps of Gibraltar in Faro.

Matty Lusty put Larne ahead with a long-range effort after 16 minutes, but Kike Gomez soon had the hosts level with Spanish midfielder Joe completing the turnaround shortly before half-time when he slotted the ball home following a free-kick.

Luckless Daniel Oyegoke's own goal deep in second-half stoppage-time gave Viktoria Plzen a narrow 1-0 advantage over Hearts in their Europa League play-off tie in the Doosan Arena.

However, in the final minute of six added at the end of the far-from-thrilling encounter,
