It'll be interesting to see how quickly Poch integrates him into the first 11. I can't imagine he'll mug Trips off straight away but you got to think he won't wait long. Guess it'll come down to who's out performing who in training and how Trips performs in the games. If he has another bad game or 2 I'd imagine SA will come straight in but if Trippier finds some form and trains well then he'll have to wait I guess.
I suppose it depends how bad the injury was that forced trippier to return from international duty. I guess it was just precautions but if there is an injury then I would imagine serge will start the next match over kwp
