PIRAEUS, Greece -- Atletico Madrid slipped to a surprise 3-2 defeat to Olympiakos on Tuesday in a disappointing return to the Champions League for last seasons finalist. Atletico fell behind in the 13th minute of the Group A match when defender Arthur Masuaku aimed a left-footed drive past goalkeeper Jan Oblak, who was making his debut for the Spanish club. Striker Kostas Mitroglou unselfishly left the ball to Imbrahim Afellay who made it 2-0 in the 31st. But Mario Mandzukic pulled a goal back before the break, left unmarked to head in a cross from Cristian Ansaldi. Mitroglou scored with a stylish move that proved to be the winner in the 73rd, turning on the ball to beat Oblak, before Antoine Griezmann finally found the net in the 86th for Atletico. Griezmann was twice denied by Olympiakos goalkeeper Roberto -- who joined Atletico as a schoolboy and was loaned out by the club last year to Greece. "This is a huge win for us," said Olympiakos captain Giannis Mantiatis, who recovered from an ankle injury to make the starting lineup. "We had to sweat the whole match. These were very valuable points we got tonight." Atletico coach Diego Simeone watched from the stands at Karaiskaki stadium, as he served a one-match European ban. "We threatened throughout the game, but Olympiakos was very tough and they got a valuable win," Simeone said. Simeone defended his choice to replace first-choice goalkeeper Miguel Angel Moya, arguing that rotation was needed to cope with the domestic and European workload. "What decided the game was that they were more effective with their chances that we were," he said. "Obviously this was a very negative result for us. Clearly Olympiakos is in a good position. What we feel now is a sense of responsibility." Olympiakos coach Michel Gonzalez said his team "successfully disrupted" Atletico. "To beat a team like Atletico, you have to do a lot of things right ... We are a team like (Atletico) and do well against teams that appear to be of higher quality," the Spanish manager said. "Now we have an advantage, to be sure," he said. "All I can say is that we are very happy -- much happier than we were two hours ago." Juventus beat Malmo 2-0 in the groups other game.

Here are some of the best from Week Seven and players to watch for Week Eight: TOP PERFORMERS Bo Levi Mitchell, QB, Calgary (26-for-36, 289 YDS, 3 TD, 1 INT vs. Ottawa) - Mitchell ranks fourth in the league in passing yards this season, but is tied for the lead with 11 touchdowns and has thrown only two interceptions, giving him the highest QB Rating among CFL starters. He took advantage against the expansion Redblacks in Week Seven, completing a season-high 72.2% of his passes in a 38-17 Stampeders rout. Kendial Lawrence, RB, Edmonton (123 YDS, 1 TD, 13 touches at Montreal) - A smaller, speedy back out of Missouri, Lawrence is trying to break into the Eskimos lineup and took advantage of the opportunity presented against the Alouettes when John White (who rushed for 102 yards and a touchdown on seven carries) suffered a finger injury. Lawrence was effective both on the ground and in the passing game, hauling in a 35-yard touchdown pass to get the Esks rolling early in the first quarter against Montreal. Marquay McDaniel, WR, Calgary (9 REC, 117 YDS, 1 TD vs. Ottawa) - Someone has to benefit from Mitchells passing productivity and it might as well be McDaniel, who had his first 100-yard receiving game since Week 14 last season. The veteran CFLer had a career-high 1047 yards and eight touchdowns last season, and hes not quite on pace for that yardage this year, but McDaniel is ninth in the league with 308 yards receiving, one yard ahead of teammate Jeff Fuller.dddddddddddd PLAYERS TO WATCH IN WEEK EIGHT Since the Toronto Argonauts play twice in Week Eight, Tuesday against Winnipeg and Sunday against B.C., the logical choices to focus on for this week wear the Double Blue. Ricky Ray, QB, Toronto - Hes dealing with a depleted receiving corps, but Ray still ranks third in the league with 1687 passing yards and has the leagues second-best QB Rating (96.0) behind Mitchell. Rays productivity has dipped in the past couple games, at least in part because top receiver Chad Owens is out of the lineup, but two home games for Ray ought to provide more than enough production this week. Maurice Mann, WR, Toronto - Injuries open up opportunities. Thats standard football procedure, and its given Mann -- who didnt play last season -- another chance. As much as his game had declined, putting up a total of 57 catches for 624 yards in 2011 and 2012, Mann has adjusted quickly to rejoining the Argonauts, catching 11 passes for 137 yards in two games. Jerome Messam, RB, Saskatchewan - The latest in the line of ever-changing Roughriders runners, Messam rumbled for 126 yards on 19 carries at Winnipeg last week and should find an appealing matchup with the opportunity to face a Montreal team that has the leagues worst run defence, allowing 115.8 yards per game on the ground. That Messam played for the Alouettes last season should only enhance his motivation for another big game.
