Cape Town - Swansea City manager Paul Clement did not enjoy watching his side lose 4-0 to Manchester City in Wednesday’s Premier League clash at the Liberty Stadium.
David Silva scored twice, along with Kevin De Bruyne and Sergio Aguero, as the team at the top of the standings made light work of the side at the very bottom.
"At times it was horrible to be on the sideline watching that, seeing my side trying but suffering for long periods," Clement told BBC's Match of the Day.
"They are not the games that will decide our season but it was hard to watch at times because they were so dominant. For me, one of the best sides I have ever come across.
"So many good athletes, so many intelligent footballers and it is really hard to pin them down.
"We actually had some attempts on their goal so I am disappointed we did not get on the score sheet, but they were a far superior side to us."
Last weekend's 1-0 win over West Brom was Swansea’s only win in their last nine matches, and third all season, and Clement believes they need to dip into the January transfer market to avoid the drop.
"If we are going to sustain Premier League status, that is a must," he said.
