Naismith formally signed for Everton yesterday.
Weir saw first hand how effectively the pairing can work during his time at Ibrox and believes the duo can quickly re-establish their understanding.
"When they played together they did very well and obviously they can combine," Weir, who was consulted by David Moyes over the signing of the Scot, told evertonfc.com. "Steven can play in a number of positions and contribute in different areas. He's got a lot of strings to his bow. The fact that he can play with Nikica is an obvious benefit though and it's a nice one to have up his sleeve for the manager, I'm sure."
