Elleby Jersey Jovic at half-time, and tempers continued to boil over in the second half, with Bruno Fernandes confronting the Swi s bench at one point.While Santos refused to directly criticise the referees Robert Covington Jersey performance, he admitted his frustrations with Switzerland seemingly slowing down the game en route to a 1-0 victory.Im not going to criticise, but when a penalty is awarded that doesnt happen just like that, when theres a clear foul in midfield Then just Jaylen Hoard Jersey look at the number of fouls and time lost, he told reporters.The fourth official knows very well what happened in the game. Santos was satisfied with the second-half improvement, even ifSwi s goalkeeper Jonas Omlins heroics left Portugal a point behind group leaders Spain, who defeated Czech Republic on Sunday.At half-time, I was just saying that we have to have the ball and play differently and push them back, he added.We started very well, in the first few minutes we wanted to put the ball very quickly on Goncalo Guedes. We knew opportunities would arise and many have arisen.Portugal are Portland Trail Blazers Hoodie not in action againuntil visiting Czech Republic in the Nations League on September 24.
