Celtic may come to regret not making Jo Inge Berget's loan a permanent move as his double for Swedish side Malmo saw them only lose 3-2 away in their Champions League playoff first leg match on Wednesday and leave the Scottish champions hopes of a place in the group stage in the balance.
Elsewhere Valencia's hopes of a return to the lucrative group stages after a three year hiatus look more assured after beating last season's quarterfinalists Monaco 3-1 in Spain, the impressive Algerian international Sofiane Feghouli creating one and scoring the crucial third goal.
Ukrainian giants Shakhtar Donetsk also look nicely-placed for the group stages – they have reached it on every occasion since the 2009/10 campaign – after coming away with a 1-0 win against Rapid Vienna, who were last in the group stages in 2005/06.
Skenderbeu's chances of becoming the first Albanian side to make the group stages of a European club competition look slender after losing 2-1 at home to Dinamo Zagreb, the Croatian side coming from behind with Algerian El Arabi Hilal Soudani getting the equaliser and then in the dying second Josip Pivaric scored the winner.
Berget made Celtic pay badly for failing to keep their concentration both times after they had a seemingly comfortable two goal advantage – a bad habit that has been a feature of their recent play and the players had been warned about correcting by Celtic manager Ronny Deila.
The Norwegian – who has lost just once in seven meetings with Malmo counterpart and compatriot Age Hareide – could not have hoped for a better response as his side stormed into a 2-0 lead within the opening 10 minutes.
Leigh Griffiths – another who had warned his teammates about keeping their focus – slotted in the first after just three minutes rewarding Deila's call to start with him and not summer signing Nadir Ciftci, having been set up by a brilliant slide rule pass from Stefan Johansen, and seven minutes later Israeli international Nir Bitton heading home from Johansen's corner.

However, as in previous matches this season Celtic took their foot off the pedal and spurned several chances which came back to hurt them seven minutes into the second-half as Berget, who was on loan at Celtic last season, reduced the deficit with a superb goal, curling the ball past Craig Gordon.
That, though, appeared to be the kick in the pants Celtic needed for shortly afterwards they restored their two goal cushion as the alert Griffiths nipped in to lob the ball into the net after the visitors failed to clear their lines.
However, Berget struck again as Celtic failed to clear a corner and left the tie intriguingly balanced.
FEGHOULI LIFTS VALENCIA
Valencia also took an early lead at home to Monaco as Rodrigo was on hand to tap home after Feghouli had stolen in ahead of a Monaco defender to set up the goal.
Monaco – who had a goal in the first-half ruled out – levelled early in the second half as Croatian midfielder Mario Pasalic, on loan from Chelsea, scored but 10 minutes later Daniel Parejo gave the hosts the lead once again converting substitute Pablo Piatti's cross.
Pasalic looked to have restored parity only for Australian goalkeeper Matthew Ryan – signed earlier in the close season purposefully because the club wanted a 'keeper equal to Champions League level football – to produce a stunning save to keep the hosts noses in front.
Indeed they should have gone two clear but Feghouli's brilliant set up was not rewarded as Parejo missed the target – the impressive Algerian decided it was better to try it on his own when he next had a chance and he made no mistake to give Valencia a 3-1 lead.
Shakhtar were often second best in their match in Vienna but they used a let-off when their goalkeeper Andrey Pyatov pulled off a remarkable save late in the first-half to their advantage going down the other end to break the deadlock Brazilian Marlos slotting home.
