I don’t think there’s any point playing against Albania because you’ve got to have other players in that you may have to use.“I don’t want Eberechi Eze to play because I don’t want him to get injured because Arsenal is more important to me.“When Saka scored against Serbia and then he signalled over to the bench, I thought ‘don’t tell me that he’s injured,’ but he was talking about changing his boots.“Every Arsenal fan would have gone ‘get him off, just get him off the pitch.’”talkSPORTGroves admitted his concerns over Arsenal players’ fitness during the international break[/caption]As for Gabriel, he could now potentially miss Arsenal’s clash with Tottenham on Sunday, November 23.Groves added: “So with Gabriel, he was pulling his groin and his face didn’t look great when he walked off but you don’t know.“Obviously when they are analysed now, they have the CT scans and different sorts of scans to see what grade it is.“I’m hoping that it’s just a bit of stiffness and he might be available for the massive game we’ve got next Sunday against Spurs.“It’s just what happens. It’s part of the international break. (You) just want all your players to come back fit on the injury side again. I’m just keeping my fingers crossed for the England game tonight.“Obviously I want England to win, but if it meant that England drew or got beat but my two or three Arsenal players didn’t get injured, that doesn’t bother me. I just want to get them back.Gabriel is now a doubt for next weekend’s north London derby against Tottenham“If you said to Arsenal fans before the second international break, you’ll be four points clear at the top of the league with the fixtures we had to begin the season, I’d have snapped your hands off without a shadow of a doubt.”Gabriel has played every minute in the Premier League for Arsenal so far this season.Mikel Arteta’s side currently sit four points clear at the top of table having lost just once in 11 matches.Meanwhile, Gabriel has been part of a defence which has conceded just five goals and kept seven clean sheets.
