Chelsea hold a 'psychological advantage' over Paris Saint-Germain after claiming a 1-1 draw in the French capital in the first leg of their Champions League last 16 tie, says defender Branislav Ivanovic.

The Blues defender added another important goal to his tally with his first half header at Parc des Princes as Chelsea claimed a valuable away goal.

Edinson Cavani levelled the contest in the second half with a header of his own, but Jose Mourinho's side withstood heavy attacks at times to hold on to a 1-1 draw ahead of the second leg at Stamford Bridge in two weeks.

"It's a very important goal for the team," said Ivanovic. "Maybe we have a bit of a psychological advantage but these types of games are very difficult.

"We played well and had a lot of possession of the ball in the first half and we deserve the positive result from the first game."

Key saves from Chelsea shot stopper Thibaut Courtois helped Chelsea ensure PSG did not add to their tally and Ivanovic believes Cavani's equaliser will not count for much in the return leg.

"They have three proper strikers who play all of the game and they all wanted to score, so it is very difficult defensively to close all of those things," he added.

"We conceded the goal, but I think with this goal or without this goal changes nothing for the game in London."

Chelsea will feel confident of securing a place in the final eight of the Champions League having overcome PSG in worse circumstances last season. The Blues trailed 3-1 to the Ligue 1 champions after the first leg of their quarter final encounter but responded with a 2-0 victory at Stamford Bridge, enough to ensure their progress on away goals.
