Former Liverpool midfielder Danny Murphy insists Andrew Robertson is the superior player compared with Arsenal left-back Kieran Tierney.
Indeed, Murphy says Tierney will never be as good as Scotland's current national team captain Robertson.
Asked if Tierney can reach Robertson's heights, Murphy told the Glasgow Evening Times: "No. Robertson just has an unbelievable, consistent performance level and mentality. The fitness he has got and the quality in the final third, I say no because the level is so high.
"He has set the bar as a left-back remarkably high. "He is in the top three in the Premier League for assists and what both fullbacks are doing at Liverpool is phenomenal.
"But Arsenal have got a really good signing there in Tierney and he is only going to improve."
