Jack Grealish lashes out at match officials as Moises Caicedo goes unpunished for ugly challenge – as Man City star forced off against Chelsea to spark fresh injury concerns over Pep Guardiola

Jack Grealish was furious after Moises Caicedo avoided a red card for following an ugly challenge.

The Manchester City winger received treatment and had to be replaced by Jeremy Doku 66 minutes into the 1-0 FA Cup semi-final win over Chelsea.

Grealish was angry with officials and ranted as he took his place on the bench, his removal sparking further concerns after an injury-plagued season.

He has already missed part of the season with injury problems, but has returned refreshed since the international break and will want to avoid another spell of absence.

Caicedo was already on a yellow card and was lucky to avoid being sent off – and Grealish made his thoughts clear to fourth official Darren England.

He became angry with fourth official Darren England as Caicedo, already yellow, remained on the field.

He received treatment and had to be removed for Jeremy Doku, sparking further injury concerns.

It has been a frustrating season for the England international, who needs every minute on the pitch ahead of the European Championship.

Doku has often been favored and has been a breath of fresh air with his direct, scintillating style, while Grealish has been a more subdued version of himself this campaign.

At half-time, Frank Lampard urged Grealish to take more risks and suggested he believed he had been hampered by Pep Guardiola’s possession-based system.

Instead of trying to beat a full-back one-on-one, Grealish will now often turn inside or back to find a safe pass – no doubt an influence from Guardiola.

“The first 15 or 20 minutes I thought, every touch you go backwards,” Lampard told BBC Sport.

“I know they won the Treble last season, but you see a wonderful player here who is good at passing players. After 15 or 20 minutes he decided to do it.

“It’s better than just keeping possession and drawing other players towards it. They won the Treble and we know how great they are and it works but sometimes with Jack I feel like he’s playing sometimes the easy option.

The winger looked upset as he came out before ranting at England’s fourth official.

Even upon reaching the bench, he continued to air his grievances to officials.

“I know that’s what Pep wants him to do, keep possession, get two or three players and pass it to someone who’s not under pressure at all. He’s a very gifted player who can overtake players.

“He has to understand: When the ball is moving fast and he’s one-on-one, here’s a chance you can really get to someone. What you’re doing when you slow down and refuse to do it one-on-one head, the Chelsea players tell you “ok”.
