Gary Neville believes Pep Guardiola must win the Champions League before leaving Manchester City.
Guardiola led his men to win City’s fourth successive Carabao Cup title after beating Tottenham Hotspur 1-0 on Sunday.
City are also in the verge of winning the Premier League title, as they are currently topping the table with 10 points ahead of second placed Manchester United.
Guardiola’s side could compete for a treble this season, having reached Champions League final and will play the first leg against Paris Saint-Germain on Wednesday.
Speaking in his latest podcast on Sky Sports, Neville hailed Guardiola’s achievements – but believes his City job will only be truly done with Champions League glory.
“The big one is the Champions League and it’s a huge couple of weeks coming up against Paris Saint-Germain because if they were to win that, then they would have a great chance.
“That would be the cherry on the icing on the top of the cake of Guardiola’s reign at Man City because I don’t think he can leave without winning it.
“It would feel incomplete if he left this country without winning the Champions League.
“I know that happened in Germany, but here, Man City will give him the time to do it and it almost feels like he has to so he can say that the job is done.”
Neville also added that Guardiola could be City’s greatest manager of all time considering his achievements in the club since his arrival in 2016 from Bayern Munich.
“I think Man City may have the greatest manager of all time and we’ll look back in 10, 15, 20 years’ time… just the way he has infiltrated countries, dominated football but also influenced others, I don’t think I’ve ever seen it.
“You look at how he’s won in three different countries, he’s now dominating in this country – he’s going to win the league title in the next few weeks, that’s three in five years and these are massive achievements, playing the way they play as well, which is with technical players, dominating possession.”
