Paris: Everton marked their first appearance in Europe since the 2009/2010 season with a 4-1 Europa League win over Wolfsburg on Thursday while Celtic and Tottenham were held to draws in tricky away assignments.
The Merseysiders were ahead after just 15 minutes at Goodison Park when Ricardo Rodriguez put through his own goal after deflecting a Steven Naismith shot before a close-range header from Seamus Coleman made it 2-0 on the stroke of half-time.
Leighton Baines added the third from the penalty spot two minutes after the break with Kevin Mirallas firing home a smart fourth two minutes from time after a fine pass from substitute Samuel Eto`o.
Rodriguez grabbed a consolation for Wolfsburg with a curled free-kick past Tim Howard in the Everton goal in injury time.
The English side top H after rivals Lille and Krasnodar drew 1-1 in France.
Scottish champions Celtic came away from their trip to 1994 finalists Salzburg with an entertaining 2-2 Group D stalemate, twice being pegged back, while Spurs were goalless against Partizan in Belgrade.
Ghanaian winger Wakaso Mubarak put Celtic in the lead in the first quarter of an hour in Austria on his loan debut.
Brazilian striker Alan then levelled for the home side, his 35th minute shot deflected off defender Efe Ambrose.
Minutes before, only Celtic keeper Craig Gordon`s fingertips had kept out Andre Ramlho`s header.
After the restart, Gordon produced a superb double save to keep Salzburg at bay again.
Scott Brown put the Scots back in front on the hour, his 30-yard screamer helped on its way by Andre Ramalho`s leg.
With 12 minutes left, Salzburg captain Jonatan Soriano earned the Austrians a share of the points with a brilliant freekick, which flew over the wall and into the top corner of Gordon`s net.
Celtic boss Ronny Deila said: "It was a good result against a very good team. We worked better as a team today and stood the distance better."
On Gordon`s heroics in goal he added: "He was marvellous. He has been good all season and he is a top professional."
In the other game in Celtic`s group, on-loan Manchester United forward Angelo Henriquez was among the scorers as Dinamo Zagreb routed Astra Giurgiu of Romania 5-1.
Tottenham, in their fourth Europa League campaign, made no fewer than 10 changes from the side that drew with Sunderland in the Premier League at the weekend, keeper Hugo Lloris the only survivor.
Harry Kane almost gave the north Londoners a dream start to their bid to get out of Group C, his first minute attempt hitting the bar.
But despite looking dangerous on occasions Tottenham lacked the killer touch and were unable to find a way through Partizan`s defence.
Tottenham coach Mauricio Pochettino said: "In the end it was a tough game and difficult to do well. We tried. One point was a fair result."
"We knew it would be difficult. The result was fair. We competed and got a clean sheet," he added.
Elsewhere, Inter Milan were held 1-1 at Dnipro, and goals from Aleksandr Kokorin and Aleksei Ionov lifted Dinamo Moscow to a 2-1 Group E win at Panathinaikos.
Defending champions Sevilla enjoyed a 2-0 win over Feyenoord thanks to first-half strikes from Grzegorz Krychowiak and Stephane Mbia.
Steaua Bucharest beat Aalborg 6-0 with Claudiu Keseru scoring an 11-minute second-half hat-trick.
