Paul Pogba's agent has stirred things up on the eve of the biggest game of Manchester United's season.

Mino Raiola says the France midfielder is "unhappy" at United and "has to change teams" in the next transfer window.

Pogba, 27, has made only eight Premier League appearances this season, starting five, and scored his first goal of the campaign on Saturday.

"Paul is unhappy. He is no longer able to express himself as he would like and as expected of him," Raiola said.

A couple of games are already under way in Group F this evening.

Borussia Dortmund began matchday six top and with qualification already secure, one point above Lazio - with Club Bruges two points further back.

However, Lucien Favre's side find themselves 1-0 down at half-time against Zenit, which means Lazio's 2-1 lead in their winner-takes-all clash with Club Bruges puts them top as things stand.

Club Bruges, reduced to 10-men shortly before the interval, can only qualify if they beat Lazio. Zenit are already out.

There's significantly less excitement on offer in Group E.

Chelsea's 4-0 beating of Sevilla last Wednesday sealed qualification as group winners, with Sevilla also guaranteed to finish second.

Krasnodar's win against Rennes also means the Russian outfit will drop into the Europa League - regardless of what happens against the Blues this evening.

Manchester United only need a point to reach the last 16 - but a defeat and they're definitely out.

They will top the group if they better PSG's result.

PSG just need a point to go through - and a win to top the group. They could go through with a defeat - so long as the other game isn't a draw.

Leipzig will be through if they win - or with a point if PSG lose.

Things were looking so good for Manchester United after two games of their Champions League group - a 2-1 victory at Paris St-Germain and 5-0 thrashing of RB Leipzig.

But three points in their next three games - a home win over Istanbul Basaksehir - has left their qualification hopes going down to the final day.

Oh and Chelsea are playing too - but that one's a dead rubber.
