Elyounoussi was instrumental in helping Basel qualify for the knockout stages of the Champions League by finishing runners-up to Manchester United in Group A and he impressed in both meetings against Manchester City in the round of 16.
City collected the EFL Cup with a 3-0 win over Arsenal at Wembley, where an ebullient Mendy led the celebrations, and the runaway leaders are on course to wrap up the Premier League title over the coming weeks.
City were beaten 2-1 by the Swiss champions, their first home loss for 18 months, but it did not prevent them going through to the Champions League last eight 5-2 on aggregate.
Delph was suspended for three matches, following his red card in the FA Cup defeat to Wigan, but missed the midweek Champions League visit of Basel through injury.
He was not happy with the display, though, saying his players "forgot to attack" and is hoping for better when they travel to relegation-threatened Stoke on Monday. "Like everybody knows, hopefully sooner or later I can stop wearing it (the ribbon)".
"We have one or two training sessions until the game".
Guardiola's side need a maximum of 12 points from their final nine matches to win the Premier League title but the manager has warned that easing off will lead to problems. Fabian Delph is [uncertain]. They also have a chance to become the first team to break the 100-points barrier in the history of the English top flight.
"We are not in the quarter-finals and we are not the champions yet though".
"I don't know if the players can be ready, but we are going to work on that these next few days".
Paul Lambert's Stoke are involved in a fight for survival, sitting in the relegation zone, and Pep foresees a hard game on Monday.
"Sometimes in Barcelona, I remember when we played on Monday, a long time ago, always it was not good". City thrashed the Potters 7-2 when they met earlier in the campaign but Guardiola is not thrilled about the prospect of a trip to the bet365 Stadium on a Monday night.
