IMO, uninteresting fight. and yes, according to what I previously suspected that the home team will play with defensive tactics. in the end, Rennes was able to overthrow PSG and the tactics implemented by Bruno Genesio went according to plan. Initially I thought Galtier would play Mbappe in the main starting line-up in this match.
Before, my estimation PSG will overthrow the home team easily. however, not what I expected. yes, it turns out that Galtier is trying to experiment again in this fight. from the last two matches, PSG did not play with its best performance. there were several opportunities they had, unfortunately the Galtier troop squad was unable to convert them into goals. I think this match was a lesson for the PSG coach. that his squad still has some weaknesses, in particular the line of attacking midfield and reserve players is not on par with the first team. at the very least, Galtier should bring in a newcomer.
For Lens, I doubt Lens will go smoothly. the reason is, they have tough matches against quite strong teams in the next few weeks.
I have to say that Galtier or whoever he is (never even heard of him before he got to PSG) was the wrong choice, this is the reason why they are playing so close to Lens as well. Any decent manager would have taken this team to 10+ point difference and finished as leaders of the group in UCL as well.
As long as they do not have a manager with a great tactic but also understands the language of superstars, they are going to fail, even if they win, they will win by being worse than expected in the end. This is why I insisted on Zidane so much, give him the highest salary any manager ever got if you have to but he would have ben amazing for this team without a doubt and won everything.
